Bright Sword Military System

What Wang Xuexin is talking about is actually an NPN type triode, where "N" means the part doped with phosphorus and has one more electron, and "P" means the part with boron doped with holes.

Wang Xuexin studied "Digital Circuits" when he was in college, and it talked about three-stage tubes. At that time, he used the "high-speed rail station" method to understand NPN-type three-stage tubes:

There is a long queue at the high-speed rail station to go through the security check. There are empty seats (cavities) in the waiting room, and the flow of people can enter the waiting room smoothly.

When I got on the train, I found that the high-speed rail was already full of people, so I couldn't get on the train.

At this time, as long as the people who arrive at the station get off the train first, the flow of people can get on the train and the whole station can run smoothly.

The NPN triode is almost the same. It just treats people as electrons and seats as holes. It is no problem for electrons to go from the first "N" to "P", because "N" is redundant. Electrons and "P" have holes, and electrons can enter the holes smoothly (this is equivalent to entering a waiting room with vacancies).

But the electrons from "P" to the second "N" will not work... "N" also has excess electrons but no holes, so it is like a high-speed rail full of people and no one can squeeze into the train.

At this time, you only need to use a reverse small circuit to let the electrons of the second "N" flow to "P", that is, let the people who arrive at the station get off first, and then all the roads will be smooth.

In other words, it is this "small circuit" that can control the smoothness of the "big circuit": when the "small circuit" is turned on, the "big circuit" is also turned on, and when the "small circuit" is turned off, the "big circuit" is also turned off... This is similar to relays and electronic tubes. In fact, it is the same thing, so it can be used as the computing unit of the computer.

Don't underestimate this invention. The three scientists who invented it won the Nobel Prize in Physics.

But of course, although the theory is simple, it is still difficult to implement it, and the difficulty is not small.

The difficulty is to produce high-purity single crystal silicon... General semiconductor devices require a purity of six or more.

(Note: The requirements for large-scale integrated circuits are higher, requiring more than nine nines. Modern technology can already produce twelve nines of single crystal silicon.)
After producing high-purity single crystal silicon, phosphorus or boron should be doped into these single crystal silicon to form "N" or "P" part.

The reason why Wang Xuexin took so much effort to "rent" Turing is this...

Huaxia did not produce monocrystalline silicon technology, but the sun never sets has already been realized.

Wang Xuexin cannot directly propose to import monocrystalline silicon or its production technology to the Sunshine.

You must know that the sun never sets has computers and can also produce monocrystalline silicon. In principle, the sun never sets is much ahead of China in terms of semiconductor technology. Their scientists just didn't expect to be able to form NPN transistors by doping phosphorus and boron. .

If this was before the advent of Huaxia Computer, Wang Xuexin would still be able to safely and boldly import monocrystalline silicon or technology from Sunbuset.

but now……

The Eighth Route Army has already produced relay computers and electronic tube computers, and the eyes of the everlasting sun are already red and big, staring at Huaxia, to be precise, at the Eighth Route Army:
These country bumpkins can beat the computer twice before the sun sets?
What a shame that the sun never sets!
Now that the Eighth Route Army has exposed the technology of electronic tube computers, does it mean that they are about to enter the next generation or have entered the research and development of the next generation of computers?

This time it will never be difficult for the Eighth Route Army to take the lead...

Therefore, the Eighth Route Army is highly sensitive to importing any equipment from Sun Never Set or even Yingjiang and Mao Xiong, not to mention importing semiconductors and their technologies. This is almost telling Sun Never Set that the next generation of computers will be upgraded using semiconductors.

What would happen if the sun never set and realized this?
With the virtue of never setting the sun, they will do everything possible to block or delay the semiconductor technology of the Eighth Route Army. On the other hand, they will increase the research and development funds in semiconductors and their goal is very clear, which is to upgrade computers.

Although Wang Xuexin has a system and technology, he suffers from no equipment, no materials, and no technicians to make these materials.

At that time, it is likely to be preempted by the never-setting sun, that is, the never-setting sun will enter the era of transistor computers, but Huaxia will be in trouble because of the conscious suppression of the never-setting sun.

As the saying goes, "You must have the heart to harm others and the heart to defend against others." For the sake of the future of China and the Eighth Route Army, Wang Xuexin had to deal with it carefully.

Turing and his team were "rented" by Wang Xuexin for two years. During these two years, they could not have any contact with the sun that never sets... Wang Xuexin can easily do this, after all, this is in China and it is still in the army.

Therefore, Wang Xuexin can safely and boldly use Turing to build China's own semiconductor technology and train a group of semiconductor R&D personnel and technicians.

As for whether Turing will bring technology back to the never-setting sun two years later... At that time, the Eighth Route Army had already developed integrated circuits and sold these technologies to the never-setting sun, so there was no need to worry about leaks?

Under Turing's explanation, the unconvinced Joan also understood. She looked at Wang Xuexin and said awkwardly: "Sorry, Comrade Commander! You are right, this idea is great, but I don't understand...how did you Thinking of this? You don't even have semiconductor research and industry!"

"I've read Dr. Wilson's works!" Wang Xuexin was talking nonsense, he hadn't read any works.

Wang Xuexin doesn’t need to look at it. The great inventions of this period and even the things that can win the Nobel Prize in Physics are just the most basic things in modern university textbooks.

Seeing that Joan was still in disbelief, Wang Xuexin added: "We happen to have this need, Joan! You know, it's like N pole to P pole, Dr. Wilson's theory is like 'excess electrons', And what we need in Hida is the 'hole', so it's a matter of course!"

Turing laughed "hehe": "It's a very vivid metaphor, Comrade Commander! Although I don't like wars, I have to admit that many great inventions appeared because of wars!"

This is true, such as the development of gunpowder, positioning systems, the use of nuclear energy, etc., are inseparable from war.

"But we can't be too happy!" Turing said: "It is not certain whether it will be successful, not to mention...we lack the equipment to produce high-purity single crystal silicon, and we must be able to smoothly dope phosphorus and boron into it." !"

Wang Xuexin nodded and replied: "What equipment do you need? Make a list. I will purchase according to your requirements. In addition, there are workers, assistants, etc. You can tell me everything you need, and I will do everything I can to meet your requirements. !"

"Thank you, Comrade Leader!" Turing shook hands with Wang Xuexin: "Thank you very much!"

From Turing's eyes, Wang Xuexin can see that his gratitude is from the heart... Turing didn't realize that this is what everyone needs, and scientists are simple!
