Because he thought of semiconductor components from anti-tank missiles, Wang Xuexin casually asked: "How is the research on Turing going?"
Chen Songyong turned his attention to 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, he is responsible for tracking the progress of various research projects in the institute.
As for the other staff officers... they all study combat operations and know nothing about research and development, so it is difficult for them to be qualified for this job.
Since the institute has many projects, Staff Officer Xu did not dare to say anything casually. He flipped through the documents and found the progress record of Turing Studio before reporting: "Captain, Turing's research seems to have reached a bottleneck."
, they still can’t find a good method of doping!”
Wang Xuexin didn't say anything, and took Counselor Xu to Turing's studio.
Turing's studio is independent of the research institute. Wang Xuexin specially allocated a two-story building to him and his team, and also equipped a cooking class. Everyone's food and daily life can be taken care of in the small building.
When I walked into the studio, I happened to see Turing and Qiong taking off their hoods and walking out of the laboratory. Looking at the disappointment on their faces, there was no need to ask, they must have failed again.
Sure enough, when Turing saw Wang Xuexin, he came up to him and said, "I'm sorry, Wang, there has been no progress in the experiment!"
"It doesn't matter!" Wang Xuexin replied: "No research is easy!"
Then Wang Xuexin asked again: "What's the problem?"
"Boron is better!" Turing replied: "It is a substance with a high melting point. We can dope it into molten silicon and wait for it to re-condensate. However, the melting point of phosphorus is only 44 degrees, so this method cannot be used!
So we were wondering if we could use gas to mix it in, but the amount of gas that can be incorporated into the silicon is too small, and we had to try many times to barely meet the requirements, and this would make it very expensive, which is obviously not possible!"
Wang Xuexin understood after listening that this was not a technical issue but a matter of choice.
That's how scientific research works sometimes.
For example, when Edison invented the electric light, the technical problems were solved long ago. The problem was that he could not find suitable materials 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, and it is impossible to try them one by one, so we fall into a bottleneck.
At this time, it is a matter of choice to find a material like tungsten and use it as filament... Once you choose, it will be solved. If you don't choose the right one, it will be useless.
At this time, Turing was faced with this situation. He could not find a suitable material for doping silicon.
Wang Xuexin pretended to think about it, but in fact he was calling up a solution from the system.
To be precise, he was thinking about how to tell Turing... It only took a few seconds to call up the solution from the system. The price was 10 million military coins, which was a fair price. Wang Xuexin bought it without much thought.
.
But would it be weird if I told Turing directly?
Turing and his subordinates would exclaim: "Wow, how awesome is this? We have been conducting experiments for several months and still can't find it out. You came up and said it casually and you got it right?"
Wang Xuexin organized it and said to Turing: "Maybe your idea is right, Mr. Turing!"
"Which aspect are you referring to?" Turing asked.
"Use gas to penetrate impurities!" Wang Xuexin said.
"But it's very difficult!" Turing shook his head and replied: "We tried various methods to penetrate more gas impurities, but they all failed!"
Wang Xuexin was silent for a while and then asked: "Have you tried using other gases?"
"What do you mean?" Turing asked puzzled.
Then Turing understood: "What do you mean, use 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 compounds react to form volatile substances?"
Looking at the confused Turing, Wang Xuexin said: "High-purity single crystal silicon will inevitably be mixed with oxygen in its molten state, right?"
Turing nodded.
Wang Xuexin added: "If we use a compound containing phosphorus and hydrogen to react with single crystal silicon, hydrogen and oxygen will react to form water, which will volatilize at high temperatures and take away the oxygen. At the same time, phosphorus will be doped into the silicon... You said
Can more phosphorus be doped into it using this method?"
Turing's eyes widened when he heard this, and then he 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, right away!" Turing shouted excitedly, completely ignoring Wang Xuexin beside him, as if he didn't exist.
After a while Turing shouted again: "We can also try diborane!"
This is another gaseous substance, a substance containing boron and hydrogen.
Obviously, Turing had something in mind: If phosphorus can be doped in this way, can boron be doped in the same way?
This doping method will be much simpler and easier than the original method, so the cost can be reduced.
Then the studio became busy. Turing and others, who had just taken off their hoods and were about to take a rest, walked into the laboratory "fully armed" again because of Wang Xuexin's words.
Seeing this scene, Wang Xuexin breathed a sigh of relief. Now the problem should be solved, right?
If it still can't be solved, then it's not worth the effort he put into "renting" 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 to Wang Xuexin excitedly after answering the phone and said: "The team, the team leader... succeeded!"
They succeeded in doping impurities evenly into single crystal silicon!"
Wang Xuexin nodded, this was the end of one of his worries.
When Wang Xuexin returned to Turing's studio, there was already a scene of jubilation, with everyone hugging each other and cheering.
When Turing saw Wang Xuexin, he came up to him excitedly and said incoherently: "Comrade leader, I, I don't know what to say... thank you or something else! In short, you are so amazing! How do you know how to use compounds
Of? I mean phosphine..."
"Nothing!" Wang Xuexin shook Turing's hand: "That was just an accident. We in China have a saying called "A wonderful hand comes by chance," 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.
Because, if it’s not a “wonderful hand”, what could it be?
Could it be that...the leader of the Chinese regiment in front of him already knew the answer?
Turing vaguely felt that this might be correct, but he had no evidence, and it was not logical!
