Bright Sword Military System

Chapter 1502 Semiconductor Components

Because anti-tank missiles thought of semiconductor components, Wang Xuexin asked casually: "How is the research on Turing going?"

Chen Songyong turned his attention to the staff officer surnamed Xu.

Staff Officer Xu's full name is Xu Qingming. Because he was a college student before joining the army and knew a lot of knowledge, he was responsible for tracking the progress of various researches in the institute.

As for the other staff officers...they all study combat and know nothing about research and development, so it is difficult for them to be qualified for this job.

Since there are many projects in the research institute, Staff Officer Xu didn't dare to speak casually. He flipped through the documents and found the progress record of Turing's studio before reporting: "Head, Turing's research seems to have hit a bottleneck. , they still can't find a good way to dope!"

Wang Xuexin didn't say anything, and took Staff Officer Xu to Turing's studio.

Turing's studio is independent of the research institute. Wang Xuexin specially assigned him and his team a small two-story building. In addition, there is also a cooking class. Everyone's food and daily life can be solved in the small building.

Walking into the studio, I saw Turing and Joan taking off their hoods and coming out of the lab. Seeing the disappointment on their faces, there is no need to ask, it must have failed again.

Sure enough, Turing greeted Wang Xuexin when he saw Wang Xuexin, and said, "I'm sorry, Wang, the experiment has not progressed!"

"It doesn't matter!" Wang Xuexin replied: "No research is easy!"

Then Wang Xuexin asked again: "Where is the problem?"

"Boron is better!" Turing replied: "It is a material with a high melting point, we can dope it in molten silicon and wait for it to re-condense, but the melting point of phosphorus is only 44 degrees, so this method cannot be used! So we wondered if we could mix it in with a gas, but the amount of gas that can be incorporated into the silicon is so small that we have to try many times to get there, which would make it very expensive, obviously not possible!"

Wang Xuexin understood after listening, this is not a technical problem but a problem of choice.

Sometimes scientific research is just like that.

For example, when Edison invented the electric lamp, the technical problems were actually solved long ago. The problem was that no suitable materials could be found for making filaments, so the lifespan was short and the cost was high.

At the same time, there are so many materials in the world, it is impossible to try one by one, so we are stuck in a bottleneck.

At this time, it is a matter of choice to find the material of tungsten and use it as the filament... If you choose it, it will be solved, and it is useless to toss if you don't choose the right one.

At this time, Turing was facing this situation, and he could not find a suitable material for doping silicon.

Wang Xuexin pretended to think about it, but in fact he called up the solution from the system at this time.

To be precise, he was thinking about how to tell Turing... It only takes a few seconds to call out the solution from the system, and the price of 1000 million military industrial coins is quite reasonable, so Wang Xuexin bought it without much thought.

But wouldn't it be weird if you told Turing directly?
Turing and his subordinates will exclaim: "Wow, so awesome? We haven't been able to find out after several months of experiments. You just said it right when you came up?"

Wang Xuexin organized it, and said to Turing: "Your thinking may be right, Mr. Turing!"

"Which aspect are you referring to?" Turing asked rhetorically.

"Use gas to infiltrate impurities!" Wang Xuexin said.

"But it's very difficult!" Turing shook his head and replied, "We tried various methods to infiltrate more gas impurities, but all of them failed!"

Wang Xuexin was silent for a while, then asked: "Have you tried using other gases?"

"What do you mean?" Turing asked puzzled.

Then Turing understood: "You mean, use a compound gas containing phosphorus? No, no, that is high-purity single crystal silicon, Comrade Leader, it cannot be mixed with other elements, except phosphorus..."

Wang Xuexin asked again: "What if the compound reacts to produce volatile substances?"

Looking at Turing with a confused face, Wang Xuexin said: "It is inevitable that high-purity single crystal silicon will be mixed with oxygen in the molten state?"

Turing nodded.

Wang Xuexin also said: "If we use a compound containing phosphorus and hydrogen to react with single crystal silicon, hydrogen and oxygen react to form water, which volatilizes at high temperature to take away oxygen, and at the same time dope phosphorus into silicon...you say Is it possible to dope more phosphorus with this method?"

Hearing this, Turing couldn't help but widen his eyes, and then suddenly shouted: "Phosphine, we need phosphine, find it immediately!"

The researcher also got busy, and Joan replied: "We don't have phosphine!"

"Then make it, immediately!" Turing shouted excitedly, ignoring Wang Xuexin at the side, as if he didn't exist.

After a while Turing called again: "We can also try diborane!"

This is another gaseous substance, one that contains boron and hydrogen.

Obviously, Turing thought of a point: If phosphorus can be doped in this way, can boron be doped in this way?
This doping method is much simpler and easier than the original method, so the cost can be reduced.

Then the studio became busy, and Turing and others who had just taken off their hoods and planned to rest entered the laboratory "fully armed" again because of Wang Xuexin's words.

Seeing this scene, Wang Xuexin secretly breathed a sigh of relief, the problem should be solved now, right?

If it still can't be solved, then it's not worth it for him to spend so much effort to "rent" the Turing team.

The result did not disappoint Wang Xuexin. At two o’clock in the afternoon that day, five hours after Wang Xuexin told Turing’s method, Staff Officer Xu ran up to Wang Xuexin excitedly after answering the phone call, saying, “Regiment, regiment leader...it’s a success! They succeeded in uniformly doping impurities into single crystal silicon!"

Wang Xuexin nodded, this is considered to be a solution to one of his heart problems.

When Wang Xuexin returned to Turing's studio, there was already a jubilation, everyone was hugging and cheering.

When Turing saw Wang Xuexin, he greeted him excitedly, and said incoherently: "Comrade leader, I, I don't know what to say... thank you or something else! In short, you are amazing! How do you know how to use chemical compounds? of? I mean phosphine..."

"It's nothing!" Wang Xuexin shook Turing's hand: "It was just a coincidence. There is a saying in China called "Miaoshou Occasionally Obtained", which refers to this situation! I only thought of this because of the gaseous mixing method you mentioned! "

Turing still couldn't believe it, but he had to believe it.

For what is this, if it is not "accidentally obtained by a wonderful hand"?

Could it be that... the head of Huaxia in front of him, he already knew the answer?
Turing vaguely felt that this might be correct, but he had no evidence, and it was not logical at the same time!
