Hand rubbing nuclear fusion live in the wilderness

Chapter 173 Carbon-Based Chips
Looking at the secondary task reward on the virtual screen, Han Yuan's Adam's apple twitched, and he couldn't help swallowing.

Turning over and standing up, he ran back to the study and turned on the computer, searching the Internet for information about chips.

[Carbon-based chips, bionic robots, Metaverse, hyperspace concerts... The Yunqi Conference is about to open, and core technologies will be released heavily. 】

[Carbon-based chips became Huawei's life-saving straw, and Huawei voluntarily disclosed its patents, triggering a duel between Huami's carbon-based chips. 】

[Silicon-based chips are about to reach their limit?TSMC spread the good news again, and my country has already laid out the layout. 】

[The physical limit of silicon-based chips is seven nanometers, why is TSMC still able to make five-nanometer chips?]

【Research progress on monolithic integration of silicon-based optoelectronics and microelectronics】

On the webpage, one piece of information related to the chip came into Han Yuan's eyes.

After more than ten minutes, he finally put down the mouse, fell back and leaned on the back of the chair.

Silicon-based chips have another name, called 'silicon-based optoelectronic integrated chips'.

Judging from the naming, this 'carbon-based integrated circuit board' can almost be confirmed as a concept in integrated chips.

I just don't know what kind of situation this integrated circuit can achieve?
Can it break through the limit of silicon-based chips?
For this, Won is looking forward to it.

You know, traditional silicon-based chips have limits.

This is the physical limit, which is determined by the diameter of silicon atoms and silicon lattices. The diameter of silicon atoms is 0.117 nanometers, but the diameter of silicon lattices is about 0.5 nanometers.

When the silicon-based chip breaks through 1nm, the quantum tunneling effect will make the "electronics go out of control" and the chip will completely fail.

To be precise, traditional silicon-based chips already have quantum tunneling effects at 5nm or even below 7nm.

But later scientists broke this limit by constantly changing the material of the transistor.

The world's smallest transistor is molybdenum disulfide with a gate length of 1 nanometer.

But no matter how you change the material of the transistor, where are the physical characteristics of the silicon substrate?

In other words, the limit of silicon-based semiconductor materials is destined to be one nanometer.

Below a nanometer, electrons shuttling through a transistor can directly break through the lattice structure of the silicon substrate, causing electrons to scramble.

This is the so-called 'quantum tunneling effect' and is the limit of silicon-based chips.

However, this is only a theory. In fact, due to physical limitations, silicon-based chip technology can reach two nanometers is almost the limit, and silicon-based tubes cannot be smaller.

One nanometer, that's almost black technology.

Therefore, if the chip wants to develop further, it is necessary to find other materials to replace silicon semiconductors.

Won also knows some news about carbon-based chips.

After all, there was a lot of noise on the Internet a few years ago.

What carbon-based chip corner overtaking.

What silicon-based chips are forced to monopolize, my country's development of carbon-based chips breaks the Western blockade.

All kinds of related news are everywhere on the Internet, and it's not like he just connected to the 2G network in the village.

At that time, he hadn't graduated yet, so he was still very interested in this kind of thing.

After all, if something like a carbon-based chip can be developed, Huaguo's take-off will be doomed, and no one can stop it.

If you really want to say that he can't do everything for the country, but it doesn't mean that he can't be happy for the country's rapid development.

But after occasionally talking about this topic with the school professor later, Han Yuan let go of this idea.

The professor was very straightforward.

He said that carbon-based chips are not a new concept, as early as 30 or [-] years ago.

But until now, even the theory has not been completely resolved, and the related papers on major subjects are extremely serious.

He doesn't have much hope for something that hasn't even been completely solved theoretically.

Even if carbon-based semiconductors have lower cost, lower power consumption, and higher efficiency, it is still unknown how many years in the future.

If carbon-based chips are really so easy to solve, why are silicon-based chips the mainstream now?

Compared with the status of a scumbag in the past, the current Han Yuan can be said to be a real academic master.

The various knowledge and information in his mind are enough to support him to make some analysis and judgment.

Not to mention the difficulty of making chips, just in terms of the properties of the two elements silicon and carbon, the two are not at the same level.

Compared with silicon, the nature of carbon is more than a little bit more active.

Although it is not difficult to use carbon-based conductors, it can even be said to be very simple. He can make them by himself now, and the most common graphite can conduct electricity.

But it is very difficult to use carbon-based semiconductors.

Because semiconductors not only need to conduct electricity, but also need controllable resistance.

Carbon-based can do this step, but it is extremely difficult to manufacture.

Even if the difficulty is high, the most important thing is that the carbon atom has only two layers of electrons, which is very active and can easily lead to structural instability.

For a chip with extremely high precision and extremely thin transistors, stability is a necessary requirement.

In this regard, the intrinsic defect concentration of silicon is extremely low, which means that it is completely explosive in terms of stability.

Therefore, Han Yuan never thought that there would be such a reward for the second-level task.

As for the reward of the second-level task, this really gave him a surprise.

Since this system will issue 'carbon-based integrated circuit boards' as rewards.

Then this proves that in the eyes of the system, carbon-based integrated circuit boards are a feasible path.

Now let's see how far the carbon-based integrated circuit board preparation information rewarded after completing the task can go.

But even rudimentary or entry-level stuff can do Won and the world a huge favor, can't it?

At least let him know how to go in the direction of the carbon-based integrated circuit board.

In fact, Won doesn't care much about some technologies that will inevitably appear in the follow-up live broadcast.

After the development of the past year, he now enjoys the feeling of overcoming difficulties and harvesting results bit by bit in the development process.

If he wants to pretend, he develops various technologies in the live broadcast room, and then reaps the amazement of the audience and the shock of researchers from various countries.

This feeling is also very good.

Even later, such as when carbon-based integrated circuit boards are manufactured, the feeling of leading the development of the entire human civilization behind the scenes will be even more refreshing.

After thinking about it, Han Yuan got up and opened his mailbox to send an email to his laboratory.

Let the laboratory supervisor arrange for someone to collect some latest news and related scientific and technological information about carbon-based chips.

He still wants to know what progress human society has made in this convenient way.

At least the things collected by professional laboratories are much more reliable than all kinds of messy news on the Internet.

After sending the email, Won opened the personal information panel.

The first-level task is completed, the reward is also in hand, and there should be some changes in personal attribute information.
