Hand rubbing nuclear fusion live in the wilderness

Chapter 538 A Brand New Chip
Through precise temperature control, Han Yuan disassembled the pale white chip that he took off from the base of the nutrition cabin.

The reason why this one was removed instead of the one taken from the ancient Warnabi snake was not because of the large number of them. There is one in each nutrition cabin, so it doesn't feel bad even if it is damaged.

There is only one dark green chip, and it is still a chip that can perfectly fit creatures. If it is damaged, he will have no way to study it.

The biological specimens in the biological laboratory of the Sahara Eye underground base do not contain such chips, and he has dissected them.

So to be on the safe side, it is safe to study the chip with a backup first, to ensure that it is safe and does not damage the internal structure of the chip, and then come out with the dark green biochip.

The chip base disassembled by temperature control technology was removed, and the square chip core was exposed to the eyes of the Korean won and the audience in the live broadcast room.

Not only the Korean won was curious, but the audience in the live broadcast room were also curious about what this thing that looks like a computer chip is, and what is the structure inside.

In particular, experts from various countries are even more curious about this kind of thing.

A "biotechnology" civilization that is completely different from human civilization and more advanced than human civilization can produce chips that will definitely bring great help to the development of human chips.

Inside the light white metal case, there is a flat protrusion on the base, which is similar to the structure of a modern chip.

However, the detailed structure of this kind of thing cannot be seen by simply looking at it with the naked eye, and can only be observed with a microscope.

Magnified hundreds of times, the core structure is revealed in front of Won.

It looks completely different from the structure of a computer chip.

Ordinary computer chips are processed on single crystal silicon materials by photolithography machines.

Because of the use of etching, developing, doping, overlapping and other methods, the core of the chip will look like a city with tall buildings and roads when it is magnified under a microscope.

But right now, the chip that was removed from the base of the life support cabin has nothing to do with a miniature city.

More like a forest.

Through the microscope, Han Yuan clearly observed the 'vertical poles' standing on the pale white metal base,
The shape of these vertical rods is a bit like a matchstick, and the top of the vertical rod is staring at a translucent rhombus material, but compared with the matchstick, the proportion of the vertical rod is smaller, and the whole is slender like a stick Like hair.

Chips with this structure are completely different from silicon-based chips and carbon-based chips engraved with a lithography machine.

Although there are differences in consumables between silicon-based chips and carbon-based chips, the internal circuit diagrams, logic circuits, and logic gates of the chips are still interoperable.

It realizes computing functions by controlling the switches of logic gates.

As for these things like street lights in the city roads, Han Yuan didn't understand how these things could realize the function of 'logic gate'.

Is it possible that once this thing is turned on, it is turned on once, and once it is turned off, it is turned off once?
But if this is the case, how does the current or the information carried and transmitted by the radiation particles used pass to the next 'street light'?

By the underlying metal floor?
However, under the observation of the microscope, the metal floor is a completely connected whole, just like a steel plate, the whole is connected together.

Passing information through the underlying metal backplane is fine, but how do you control the direction in which the radiation particles travel?
This is like running alone on a prairie without roads, he can run in all directions at will.

If you can't control the direction of radiation particles, then you can't perform computing functions at all.

This is like the electrons in a chip are strung together everywhere, and the logic circuit has no fixed path at all.

In this way, even if the data can be calculated, it will only get wrong data.

For example, let this chip calculate a 1+1, and the final output result may be 2, 3, or 11917 and other numbers.

A chip that can't control the current, that is, the 'computing medium', is pointless.

Unless there is something on the base plate that he doesn't know, it is unlikely that radiation particles can be heard through the base plate.

In this way, the line can be ruled out initially.

And the way to realize the computing function of this chip is probably completely different from the method of silicon-based chips and carbon-based chips.

Moreover, the efficiency of this method is likely to be higher than that of the logic circuit used in carbon-based chips and silicon-based chips to calculate data.

After disassembling and studying the chip, Han Yuan sent the disassembled chip to the testing center for testing and analysis.

From materials to structures, to observing the transmission method of radiation, etc., when the complete and fixed inspection process is completed, half a month has passed.

"This is, diamond?"

Won was a little surprised when he got the material inspection report for the 'street lamp' structure in the core area of ​​the chip.

In this chip, the translucent structure at the top of the street lamp turned out to be a special form of diamond.

Diamond, this material won't be familiar.

This kind of the hardest thing among all the materials that have been found in nature is actually not widely used.

Diamond is a material with simple carbon atoms connected to each other by tetrahedral bonding to form an infinite three-dimensional framework. It is a typical atomic crystal structure.

Since the CC bond in diamond is very strong, all covalent electrons are involved in the formation of covalent bonds, so there are no free electrons, so diamond is not only hard, but also has a very high melting point and is non-conductive.

Based on its hardness, this thing is generally and mainly used in the industry to manufacture various abrasive tools, drills and cutting tools.

As for other industrial uses, the performance of diamond is not very good.

Although its hardness is top-notch, it is non-conductive and has a low ignition point. Its ignition point is only 720-800°C in pure oxygen, and it is only 850-1000°C even in ordinary air. This ignition temperature cannot meet the needs of many materials. requirements.

So the industrial use of diamond is actually quite narrow.

Of course, this thing is of high purity, and it is quite widely used as an IQ tax.

Even in the current situation where large quantities of artificially synthesized diamonds and even nature are produced in large quantities, the price of one-carat gem-level diamonds is still not low, far exceeding that of gold.

Won was quite surprised to see a material like diamond in this chip.

However, the study of this diamond has discovered some special properties.

That is the diamond in this kind of chip. From the analysis of its composition, it does not show a pure carbon structure.

In addition to the original carbon structure of diamond, it also contains a certain number of nitrogen atoms and gallium lanthanide silicon molecules.

This is why it is not a highly transparent state.

Won speculates that nitrogen and gallium lanthanide silicon may be the core reason why this chip completes the function of "circuit computing" logic circuit computing data.

The data of the subsequent radiation transmission test confirmed this point.

When a certain amount of energy stones are poured into the chip for radiation, these 'street lights' made of special diamonds light up quickly.

And this kind of 'street light' that lights up does not emit light in 360 degrees without dead ends like ordinary light bulbs.

It is more like a laser emitted by a laser pointer, showing a straight-line propagation, starting from one street lamp, pointing to and passing on to the next street lamp.

This ability means that it can control the direction of the current and switch the current continuously to realize the calculation function of the logic circuit, just like the processed chip.

The most important thing is that in the follow-up high-frequency intermittent radiation conduction experiment, it was confirmed that this kind of diamond can not only realize light-guided propagation and radiate particles, but also resist ultra-high-frequency intermittent radiation conduction.

To put it simply, you keep switching on and off the light bulb in the bedroom, from once a second, to ten times a second, to a hundred times a second.

In this case, a low-quality bulb may burn out directly ten times a second.And this kind of diamond can withstand 30 switches per second.

Although it's a bit awkward to describe this top-level high-tech in the form of a light switch, but the principle is the same.

After it can resist high-frequency intermittent radiation, and can stably transmit radiation particles and light guides, and can control the routes of the two, this kind of diamond already has the function of a logic circuit. Under suitable conditions, it is completely possible to achieve data calculation OK.

"It's really another route, but the underlying architecture and computing foundation are the same."

"Carbon-based chips and silicon-based chips realize the computing function of logic circuits by controlling the switching of current."

"This kind of diamond realizes the computing function of logic circuits by controlling light radiation and particle radiation."

"And its bandgap is quite small, and its energy conduction ability is particularly strong. It can even be said that it directly changes from an 'indirect bandgap' to a 'direct bandgap'."

"In this way, the calculation efficiency can be increased by at least ten times, and if it is high, it can reach hundreds, thousands or even tens of thousands of times of the indirect band gap."

"It's no wonder that there aren't that many logic gate structures in this chip."

"."

In the laboratory, Han Yuan sorted out the research data for this chip.

Although there is no progress in research on such things as this chip, how the materials inside are made, how to control particle radiation, and the angular intensity of light radiation.

But at least the operating mechanism of this chip is understood.

In computer chips, the electronic bandgap is a very, very important property of semiconductor materials.

The energy difference between the lowest point of the conduction band and the highest point of the valence band is also called the energy gap.

It is an important index to judge the change of physical properties of materials with elastic strain, and it determines a series of things such as high-power or high-frequency device performance and life.

The larger the band gap, the harder it is for electrons to be excited from the valence band to the conduction band, the lower the intrinsic carrier concentration, and the lower the conductivity.

In simple terms, the larger the band gap, the lower its conductivity, and the smaller the band gap, the higher the conductivity.

For example, the band gap of metallic materials is much smaller than that of non-metallic materials, which is why the conductivity of metals is stronger than that of most non-metallic materials.

There are two kinds of electronic band gaps of materials, one is indirect band gap and the other is direct band gap.

In contrast, electrons in direct bandgap semiconductors are more prone to transition.

Because in the direct bandgap, electrons can jump directly to release photons, no change in momentum is involved.

And this special diamond is a special diamond made by stretching.

It forcibly stretches the original gap band gap of diamond to the level of direct band gap, which greatly reduces the energy level loss of light radiation and particle radiation penetrating it, and thus reduces energy consumption.

In the case of the same performance, if the energy consumption of a silicon-based chip is 10, then the energy consumption of a carbon-based chip is 1, and this diamond chip is 0.01.

Energy levels vary greatly.

If we ignore particle radiation and only look at optical radiation, this diamond chip is almost the "core chip" of a "photonic computer" in the traditional sense.

Because it uses optical signals for digital operations, logic operations, information storage and processing.

But here, the core calculation particle should be the H particle emitted from the energy stone, and the role of light radiation should be to build a path for the transmission of the H particle, so as to fix the transmission of the H particle so that it will not go astray.

If it is a problem in a silicon-based chip, it is roughly equivalent to solving the "quantum tunneling effect" that occurs at the low nanometer level.

Well, it can be understood like this.

However, this thing is advanced, but it is a completely different system from the carbon-based chips used by South Korean won.

Although there is a certain reference value, judging from the current findings, it does not help much.

What's more confusing to Won is that there are less than 600 lampposts in a chip, at least the number of lampposts in the diamond chip in his hand for research is less than [-], only more than [-] .

For example, the number of silicon-based chips and carbon-based chips can be billions or tens of billions of transistors, and the number of [-] lampposts is not even a fraction.

At present, the function of the lamp post is consistent with the function of the transistor in the carbon-based silicon-based chip, and they all play the role of controlling the "medium signal".

This means that the performance of this diamond chip should be much lower than that of silicon-based chips and carbon-based chips.

But in fact, judging from the performance of the computer-like device in the eyes of the Sahara, the performance of this diamond chip should exceed that of carbon-based chips and silicon-based chips.

This is something that Korean Won does not understand.

Theory told him that the performance of diamond chips was lower than that of carbon-based chips, but the facts told him that the performance of this thing far exceeded that of carbon-based chips.

There was a confrontation between theory and reality, which was probably the first time he had done scientific research in these years.

However, if the reason can be found, it may be a qualitative leap for the computing power of the chip.

The computing power generated by less than 1 lampposts can be compared to silicon-based chips with tens of billions of transistors. What if there are tens of billions of lampposts?
To what extent is the computing power so terrifying?
