Reinhardt, there is no mistake, the last harvest of Spanish gold, Reinhardt was very successful, Ciric believes that this time the French gold, will also be able to pocket. Pen "Fun" Pavilion www.biquge.info

With this amount of gold, Germany's cause will surely be successful! Ciric believes that with his own travel, this time and space is no longer the same as in history.

Reinhardt was gone, it was already dark outside, and before I knew it, it was another busy day, and Ciric patted his mouth and yawned, and he didn't come home for several days.

The battle situation has stabilized, I have nothing to worry about, and now, there is no need to be afraid of someone being afraid, now, there is a joy of victory up and down.

Let's go home.

Standing up, he was about to put on his coat and go home, but his coat threw a pile of papers on the table to the ground.

This pile of documents has just been delivered, Ciric looked at this pile of documents, and shook his head, as a head of state, there will be endless things to do every day, perhaps, only a model worker like Zhu Yuanzhang likes this kind of life.

He glanced down, and suddenly, his eyes were full of surprise.

A report, impressively visible.

GEMA has successfully trial-produced a PN junction transistor!

Coming from hereafter, Ciric, of course, knows what that means.

Transistors can be regarded as opening a new door to electronic technology, and the integrated circuits of later generations are developed on the basis of transistors, and the foundation of microelectronic technology is transistors!

Ciric is quite concerned about the aspect, and has made several guidance, hoping to tinker with transistors as soon as possible.

Once, at the suggestion of Ciric, the miniaturization of the electron tube has been carried out smoothly, and the volume of various electron tubes has been successfully reduced to one-tenth of the original size.

However, this is already the limit of the tube, and the technology of the future is absolutely inseparable from the transistor, and computers, radars, sonar, and all kinds of electronic devices all need a large number of transistors.

It's a discovery across the ages!

"Führer, do you want to go home?" Guard Graff asked Shirek.

"No, go to GEMA." Ciric said.

He couldn't wait.

In World War II, many kinds of technologies were born, more than in the previous 100 years, and it can be said that war was a catalyst.

In the car, Ciric is constantly in joy, and from then on the door to microelectronics technology will be opened.

What does this mean? Your own precision-guided weapons can be further optimized, the cost can be reduced, your own radar, can be more compact, the detection range is longer, the accuracy is higher, and even meet the needs of artillery radar guidance!

Your own wireless telegraph will also be lighter, and it will be easier to implement your own frequency hopping encryption technology.

Historically, it was not until December 1947 that Bell Labs in the United States successfully developed a point-contact germanium transistor. But in fact, the development of semiconductors began a long time ago.

In the first decade of the 20th century, semiconductor materials began to be used in communication systems. Ore radios, for example, use semiconductor materials for detection.

As for the invention of the transistor, it can be traced back to 1929, when the engineer Lillianfeld had already obtained a patent for a transistor.

However, due to the state of the art at the time, the materials used to make such devices were not of sufficient purity to make such transistors unavailable.

During the Second World War, many laboratories also made many achievements in the manufacture and theoretical research of silicon and germanium materials, which laid the foundation for the invention of the transistor.

It can be said that these technologies have been paved, but they need to use more financial, material and human resources to focus on tackling key problems.

Other countries may not have realized the great significance of transistors, but Ciric is clear that in future generations, without microelectronics, it will be difficult to move an inch.

Moreover, Cillik is of course quite familiar with electronic circuits and is quite familiar with the most common PN junction in transistors.

The only thing needed is to make use of the industrial technology of this era and make it!

"Crunch," the car stopped. GEMA, has arrived.

Originally, it was just a small company, but with the support of Ciric, the scale of the company has expanded by a hundredfold, and now GEMA, the most important radar development and production company in Germany, is also a secret department.

For example, at the gate, there is the Gestapo to guard it.

Ciric's car stopped directly in front of the building, which was the company's research institute, and at this time, Dr. Hollmann, who had just received the news, ran out in three steps and two steps.

His documents were sent three days ago, and the documents of his rear scientific research institutions had to be ranked behind the army's intelligence, so he waited a few days before they were reported.

When he learned that Ciric was coming, he was extremely excited, and he couldn't hide his excitement when he watched Ciric get out of the car: "Great Führer, you are such a genius, we have succeeded in manufacturing new electronic components according to your ideas, which is a great invention!" ”

Using different doping processes, P-type semiconductors and N-type semiconductors are made on the same semiconductor substrate through diffusion, and a space charge region called PN junction is formed at their intersection.

PN junctions have unidirectional conductivity and are the material basis for many devices in electronics, such as semiconductor diodes and bipolar transistors.

At this time, Dr. Hollmann chattered to Cirek: "We have tried many times according to your design plan, and at first failed, we realized that the purity of our semiconductor materials is not enough, we have adopted new vacuum smelting equipment, and we can finally purify enough high germanium, and then, this great invention has been realized!" ”

Semiconductors, the most important thing is the purity of the material, which can only be purified by smelting in a vacuum.

Of course, this is inseparable from high investment, otherwise, no scientific research institute has such strength.

Ciric nodded: "Germanium transistors can be industrially produced, and continuous improvement of technology can reduce costs, and at the same time, silicon semiconductor transistors must also be developed." ”

Now, the cost is high, but Ciric believes that it will soon come down, and as long as you have heard of Moore's Law, you will know the speed of electronic product upgrading.

There are several kinds of semiconductor materials, but there are only two suitable for transistors, especially silicon, integrated circuits, which are completely made on silicon wafers.

"We've done research and found that if the radar uses a lot of transistors, the reliability will be about a hundred times higher." Dr. Hollmann showed a finished transistor to Ciric and held it in his hand, about the size of a peanut.

There is no filament, no gate or anything, and any vibration will not affect the operation of this electronic component, and its reliability is quite high.

(I made another mistake and nagged a chapter, as a physics teacher, I really admire the door of the transistor, and now everyone uses a mobile phone to read a book, and I have to thank the father of the transistor at the beginning!) ）
