Hand rubbing nuclear fusion live in the wilderness

Chapter 203

If the trouble point of the driver IC is that the manufacturing process is cumbersome, it requires the manufacturer to have a very high knowledge reserve.

The trouble with transparent electrodes, then, is the material.

Transparent electrode is a part used in solar power generation, flat panel/computer display.

Its main component is indium tin oxide.

Tin won hands have, but indium, he did not.

Indium is a rare metal, and its distribution in the earth's crust is small and scattered.

Even its rich ore has not been found on the earth, it only exists as impurities in zinc, iron and some other metal ores, and the highest content is only about [-]/[-].

As a planet made by simulating the earth, the mineral composition in the simulated space must not be much different from that of the earth.

Although he has a metal mineral detector to find mineral deposits, he can even see what is contained in the deposit based on the collected information.

However, many mineral deposits have been found in the surrounding area, including various metal mines such as iron, copper, lead, and aluminum, and even several rare earth mines containing indium metal. Only two of them.

One is slightly closer galena, which contains 0.00001% indium.

That is, only one ton of indium is contained in 100 million tons of ore, which basically has no mining value, and he does not have the technology to extract indium from ore with this content.

The other is sphalerite, which is more than 30 kilometers away, with a slightly higher indium content of 0.017%.

This level of indium ore has mining value, but it is estimated that it will take several months to extract a kilogram of indium from it.

So he can only find a way to replace it with other materials.

After dealing with the input device, Han Yuan returned to the living room. After recording all the materials for today, he thought about how to replace the indium tin oxide.

Up to now, he has acquired a lot of knowledge and information, both elementary and intermediate.

He also has a general idea of ​​the division of knowledge and information at the junior and middle levels, after such a long period of searching and learning.

I dare not say that it is all right, but according to his more than a year of study, the technology contained in the primary knowledge information is not enough to let people get out of the mother planet.

The technology contained in the intermediate knowledge information can allow the acquirer to go out of the parent star, but the scope of activities should be limited to the parent galaxy.

After all, this can be seen from the previous knowledge information on the application of intermediate electric energy.

As for what else is advanced and above, Han Yuan doesn't know, and he hasn't obtained it.

However, he personally guessed that the high level might be an activity in the river system?
When he came back to his senses, Han Yuan set his search targets on primary material smelting knowledge information and primary optical application knowledge information.

If there is any material that can replace the transparent electrode, it is definitely in these two pieces of knowledge information.

But after searching for a long time, others were a little tired, but they couldn't find a material that could be used to replace the transparent electrode.

It's not that there are none, but that there is nothing suitable for him now.

The transparent electrode is actually a semiconductor material, which needs to have both excellent electrical conductivity and excellent light transmission properties, and also requires a band gap greater than 3 eV.

These are two indispensable conditions.

But these two conditions limit most of the materials.

Although many materials such as indium compounds, gallium compounds, and molybdenum compounds are provided in the knowledge information, they can be used as transparent electrodes.

But these materials are the same as indium tin oxide, and he lacks these rare metals in his hands.

This really corresponds to what he himself said earlier: "The more technology develops, the more irreplaceable the corresponding materials and technology are.

Now he encountered a material problem, and for the first time he couldn't find a suitable one from the knowledge information.

"Could it be possible to really mine those two rare earth mines?"

After searching to no avail, Han Yuan looked at the distant night with some headaches.

If he really wants a substitute, he can't find it. There is a sphalerite dozens of kilometers away, which contains indium.

In addition, there are several rare earth mines, and rare metals such as gallium and molybdenum are also available.

But the mining of these mineral deposits is a very troublesome thing, because these ores are different from the previous metal mines.

He has found and smelted basically all the ores that can be found on the ground within [-] kilometers around.

The rest are buried underneath.

It is very troublesome for him to mine the ore at the bottom.

He had to get tools like an excavator first, and then he could start mining.

Otherwise, relying on manpower alone without tools, even if his physique is five times that of ordinary people, it will not help.

"If you really want to mine ore, it's better to just give up this and replace it with the original 'ray display tube' display."

After frowning for a while, Han Yuan resolutely gave up the idea of ​​mining ore. It took too much time and trouble, and it was too late.

It seems that after several days of tossing, I still have to switch back to the 'ray display tube'.

Although the knowledge learned will be stored in his brain forever, Won still has some regrets.

A more advanced and convenient device could have been used, but material problems caused him to return the original.

This kind of feeling is like the technology in the steampunk novels has developed to the point where it can fly into the sky, escape from the earth and even enter the universe, but some people are still using the technology of the steam age.

"Why don't I try to develop a new material by myself?"

Spreading out the pen and paper, just as Won was about to draw the blueprint of the 'Ray Display Tube' monitor, a thought flashed in his mind.

"Yeah, why don't I try to develop a new material by myself?"

Under the light, Han Yuan, who was sitting on a chair, was stunned, staring straight at the darkness in the distance, with this thought in his mind.

For a long time, for material problems, or most of the problems, he has relied on knowledge information or some things he already knows.

But in fact, after more than a year of systematic study, I dare not say that he is No. 1 in the world, but at least, he has already stood at the top of the pyramid.

Even on some boundaries, he has already broken through the boundaries, reaching the point where human society needs to catch up.

It's just that he has been relying on the system for a long time, so that he has not stepped out of this wall, not even in thought.

Even daily study is only the understanding and mastery of all current knowledge and information, and there are few ideas for breakthroughs in the past.

Even after being unable to get help from the system, his first thought was to return to technology and seek primitive methods.

But I never thought about my own research and development, to break through this boundary.

With his current level, it seems that it is not impossible to research and develop the same material.

Suddenly, Han Yuan seemed to see a lighthouse from the darkness, although it was very faint, it was so dazzling.
