Lu Donglai's face was a little unpleasant.

What does Bai Yi want to do, he can't go down the steps, he has to fall and break his head? Is there an application of germanium single crystal?

Professor Mendekhkin, the head of the Department of Electronic Information of the Central University of Moscow, is his mentor, and he is an absolute authority in the field of electronic information in the Soviet Union, and his influence is not only limited to the Soviet Union, but also has an important academic position in the field of international electronic information.

Of course, if the name of academic influence alone is not enough to convince Lu Donglai based on facts, the key is that Professor Mendechkin is the pioneer of the Soviet transistor, and the material he uses is the germanium single crystal that Bai Yi said.

With such a bull who can be called the father of Soviet electronic information as a mentor, it is difficult for Lu Donglai to think about the development status of the Soviet electronic information industry.

Yes, semiconductors based on germanium single crystals do have unparalleled advantages, but the problem is that the acquisition, purification and final semiconductor molding of germanium single crystals are all insurmountable technical difficulties, which is why the Soviet Union is also trying its best to realize the industrialization of germanium single crystal semiconductors.

However, due to bottlenecks in material technology and processing technology, this road is quite difficult, that is, the Minsk Radio Plant No. 1 in Belarus can barely make some unreliable germanium diodes.

Most of the rest is done in research labs.

In contrast, the tube was much more mature and reliable, and it was only in this situation that the decision-making department of the Soviet Union finally decided to focus on the development of the tube.

Lu Dong came here to develop semiconductors, but the problem is that how can things that even the Soviet Union itself can't handle can help China?

Therefore, instead of being ambitious and unrealistic, it is better to settle down and be down-to-earth, and besides, the tube is enough to meet the technical requirements for a period of time in the future.

However, looking at Bai Yi's meaning today, it seems that he is not interested in electron tubes, but emphasizes germanium single crystal-based transistors.

This has to make Lu Donglai vigilant, after all, judging from the relationship between Bai Yi and the head of armaments, the intimacy between the two is extreme, it is difficult to say that the chief of armaments is not moved, if everything is mature, it is easy to say.

The problem is that the current preparation of germanium single crystal can neither get foreign aid help, nor can it be possible to complete technological breakthroughs independently.

Thinking about the laboring masses who are still struggling on the food and clothing line, it is strange that Lu Donglai's face can be good-looking.

So before Bai Yi could start to say what he said, Lu Donglai spoke first: "As far as I know, even Britain and the United States have not fully rolled out germanium single crystals, so where is the large-scale application?" ”

"Oh? Is it? It seems that the technical intelligence blockade of the Soviet Union by Britain and the United States is quite in place! ”

Looking at Lu Donglai's ugly face, Bai Yi was still as usual, but after Lu Donglai heard this, his gloomy face was filled with unconcealable surprise for no reason, but before he could ask to understand, Bai Yi had already spoken: "Director Lu is right, from the bright side, Britain and the United States have not fully rolled out Germanium single crystal-based transistors on a large scale, and many things are still in the laboratory, but this is just a trick for them to confuse our red countries."

In fact, as early as World War II, the British used the characteristics of germanium single crystal detection to make it into a detector and amplifier and applied it to radar, thereby improving the target recognition and judgment ability of the British radar network.

The British, who tasted the sweetness, continued to study germanium along this line, and finally created the first germanium diodes and applied them to new radars.

Although it is only a two-pole device with a single conductive characteristic, its function is that in addition to rectification, it also has the functions of detection, mixing, switching and voltage regulation, not only that, the power consumption of germanium diode is small, there is almost no heat radiation, fast driving, small size and high reliability.

Of course, germanium diodes are not without disadvantages, for example, its temperature requirements cannot exceed 85 degrees Celsius, so in the case of extreme high temperatures, the reliability of germanium diodes is not as good as that of leather tubes.

But the problem is that extreme environments above 85 degrees Celsius are not common, and the corresponding heat dissipation measures will not keep up.

For example, the four-way hammer servo system on the cold forging machine modified by our Baiyun Factory, the prototype of the control component in it is actually the core equipment of the all-electric artillery stabilization system of the British Emirates tank, the gyro stabilizer and the connection controller.

In order to ensure the stability and flexibility of the whole system, the electronic components used by the British are germanium diodes and supporting heat dissipation mechanisms, and the overall structure is very exquisite, so that their chieftain tanks can still complete the tactical action of accurate artillery fire on the march under the undulating terrain of North Korea.

And we just adjusted this system a little and applied it to the synchronous adjustment of the four-way hammer, and it turned out that even the Soviets, who were above the top, had to beg us, doesn't this show the importance of transistors with germanium as the core? ”

Bai Yi said a lot of words, and everyone present was stunned when they heard it, there was no way that the amount of information in these words was too much.

People can't digest it at the first time, they can only stare at each other in surprise, and after a long time, Lu Donglai, who is considered an expert in the field of electronic information, was the first to react, and asked anxiously: "Xiaobai, where did you know what you said?" ”

Lu Donglai was surprised, but then he was deeply shocked, even his authoritative mentor in the field of electronic information in the Soviet Union did not know, how did Bai Yi, the deputy chief engineer of the small military factory, know? Does he have eyeliner in Western countries? How can it be?

"It's not a big deal, didn't we have a group of German experts in our factory before, I knew it when I chatted with them, after all, Britain and Germany were mortal enemies during World War II, and Germany had a lot of intelligence officers in the UK, and their intelligence spying on the British radar situation was far from the imagination of ordinary people, so those German experts who had used to crack the British radar technology still knew some inside information."

Bai Yi naturally couldn't say that all he had seen was from the textbooks of his previous life, so he could only carry the pot to that group of German experts, anyway, since he was reborn, the pot of German experts has long been unaware of how much to memorize, and there is naturally no pressure to have one more.

As for whether someone will check it, Bai Yi is not worried at all, even if Stottenberg doesn't admit it, then what about the diary of the mysterious German core expert, if it is really okay, all night, just write it, what can there be to worry about?

How did Lu Donglai know that Bai Yi would be so shameless as to commit academic fraud all night, he was speechless in shock, and his mouth grew for a long time before he said sneeringly: "We...... We...... Are we already lagging behind? ”
