Chapter 288 Labor Day Gift?
Gao Zhendong took a look at it and found that the requirement was quite simple, a silicon single crystal with 5 nines, and the size requirement was even smaller than the existing capabilities. It was estimated that the other party could not imagine how powerful the single crystal furnace of Gao Zhendong was.

The crystal orientation is required to grow in the (111) direction, and the doping element is phosphorus. Even the dislocation density and minority carrier concentration are involved in the requirements.

Are they going to make an N-type substrate? It seems that the other party has a very deep understanding of the role of silicon in semiconductors, and is very clear about the crystal orientation, doping, etc. It is obvious that the goal is very clear.

As soon as we see this requirement, we know that it is the substrate of some semiconductor product, but it does not involve deeper process flow. There should be subsequent processes, but these subsequent processes are not carried out in the third rolling mill.

Gao Zhendong knows more about making solar panels with P-type substrates, but he is not so clear about making solar panels with N-type substrates, and he doesn’t even think in that direction.

Because although the two have the same performance, the former is used in all aerospace applications. As a military fan, he is naturally more familiar with the former.

Therefore, he could not imagine that this thing was used to make solar panels.

This can be regarded as a kind of "reverse information gap". Gao Zhendong is not unfamiliar with solar cells, but what he knows is much more advanced than the current technology. As a result, he is not so sensitive to things of this era.

It is just like many people in previous lives were extremely familiar with 5G and fiber-optic broadband and could talk about them at will, but knew nothing about dial-up Internet access and analog mobile phones.

Gao Zhendong did not think more deeply about it. Trying to know the other party's purpose through these requests is as troublesome as trying to recognize someone through a toes. It must be an acquaintance. Generally speaking, it is not impossible, but it is unnecessary.

Gao Zhendong had no interest in delving into the other party's purpose. This thing was transferred from the Defense Working Committee, and even the other party's unit was not mentioned. It was obvious with a little thought that it was probably a user of the same level as the Desert Base. He just had to do things according to the requirements. It would be a mistake to delve into it.

However, these requirements are not troublesome. For Gao Zhendong and his team's single crystal furnace, they can be easily achieved.

Gao Zhendong accepted the task, went to the confidential workshop to transfer people, and then made production arrangements. Although the things were not complicated, the quantity was relatively large, enough to keep them busy for a while.

For some reason, many days have passed since the single crystal furnaces and silicon single crystals were reported to the 17th Ministry of Machine Building, the 12th Ministry of Machine Building, and the Chinese Academy of Sciences, but for a while, everything was calm, as if a stone had fallen into the sea. I wonder if these units have made any big moves.

This forced Yu Yuncheng to wait patiently for the completion of the project. Even though the preparations had been completed, he still couldn't spare time to do other things.

In addition, he was not a member of the confidential line of the Third Rolling Mill. Even if he was in this line at the 1761 Institute, the procedures for participating in the confidential workshop of the Third Rolling Mill would be very cumbersome. Therefore, Gao Zhendong was not going to trouble Yu Yuncheng to take charge of the matter personally.

For this kind of task, the executor must be someone from the confidential workshop. Fortunately, Gao Zhendong had made preparations in advance. When forming the scientific research team, he intentionally transferred four people from the confidential workshop into the scientific research team. They had mastered the use of single crystal furnaces and could get started directly and produce as required.

Otherwise, there would be an extra process, which is to let the people in the single crystal furnace research group first teach the people in the confidential workshop how to operate the single crystal furnace, and then the people in the confidential workshop will start production.

After arranging this matter, Gao Zhendong continued with his work.

Labor Day was approaching, but Gao Zhendong received a Labor Day gift.

This gift was brought from the Ministry of Foreign Trade. Don't get me wrong, it has nothing to do with the export products he makes, but it can be considered another export product of his.

That was the first payment of royalties for his book "C Programming" and the accompanying exercise book published by Citigroup.

Actually, Gao Zhendong had no idea that he had such an income, so when the comrades from the Ministry of Foreign Trade found him and asked him to sign to get the money, he was completely confused.

This amount of money was not small. The first batch of printing was 2000 copies of "C Programming" and 1500 copies of the matching exercise book, and they were all sold.

Citibank’s co-publisher of Gao Zhendong’s textbook is actually operating it as a textbook.

Those who understand will understand the textbooks of the Citigroup guys. Even though it is 1960 now and the purchasing power parity of the Citigroup dollar is about 6 to 9 times that of Gao Zhendong's previous life, publishers can still sell professional textbooks for dozens or even hundreds of Citigroup dollars.

What's more, Gao Zhendong's book is scarce and unique. Although the C language has not yet been fully popularized, this does not prevent the co-publishers there from raising the price. Their idea is very simple. If we can't guarantee the scale now, then we will guarantee the profit margin.

As for whether it will affect the Citigroup members' learning of new knowledge? Who cares.

Besides, if you really want to learn, there is definitely a way to solve it. Nowadays, there are no poor people who are interested in computer-related technologies. Just like many ancient IT giants who were promoted as self-made, in fact, they have nothing to do with self-made things.

According to Citigroup's tax laws, Gao Zhendong, as a non-resident foreigner, will pay a progressive tax rate of about 0.15 based on this wave of income.

Citigroup's IRS is relatively gentle towards non-resident foreigners because they have no control over them, so they only collect taxes on the part related to Citigroup's domestic economic activities.

If you are a resident foreigner, they will be very excited. All global income will be taxed, regardless of whether it has any connection with the United States. For example, those who hold green cards can easily enjoy the same treatment as the former big boss Al Capone.

At this time, the exchange rate between the Citibank dollar and the local currency was 1:2.46. This exchange rate had been fixed since 1955 and did not change until 1971 when the Bretton Woods system collapsed.

In our country, there is no personal income tax. In short, after a series of calculations and conversions, Gao Zhendong still had more than 38000 yuan in local currency in his hands after receiving the royalties from the author of "C Programming" and the accompanying exercise book from Citigroup.
Foreign exchange must naturally be used in a unified manner, and foreign-related income must be converted into local currency according to the exchange rate and handed over to Gao Zhendong.

Don't underestimate this number. It means that the income in Citibank dollars is about 1.5, which is definitely not a small number in this day and age, especially when Gao Zhendong alone can handle this foreign exchange income.

This is similar to the early days of reform and opening up, when some people sold their paintings abroad and fetched tens or hundreds of thousands of Citibank dollars, which became a typical example of export and foreign exchange earnings and was reported in the news. However, at that time, the matter was not taken seriously to that extent.

Gao Zhendong's business was so successful that all the colleagues in the Ministry of Foreign Trade were dumbfounded. His title of "the No. 1 exporter and foreign exchange earner" was well-deserved. Not only was he capable of developing export products, but he had also made remarkable achievements in exporting himself.

When Gao Zhendong received the call and rushed to the Foreign Trade Department, the person who received him and took him to handle the relevant procedures was not an ordinary staff member, but a comrade with a similar rank to Director Yang and his colleagues.

Some of the procedures were even brought by people from the Ministry of Foreign Trade and handed over to Gao Zhendong by this comrade, who then signed for the procedures. There were very few staff members from the Ministry of Foreign Trade who had direct contact with Gao Zhendong.

It seems that the Ministry of Foreign Trade is also well aware of Gao Zhendong's situation. Although they have to ask him to come in person due to complicated procedures, they are still very careful to control the scope and level of those who know about it.

In the end, Gao Zhendong got a cash check from the bank. When dealing with the Ministry of Foreign Trade, they naturally would not take out a lot of cash.

Looking at this thin piece of paper, Gao Zhendong thought to himself that this Labor Day gift was really solid.

The comrade in charge of receiving him from the Ministry of Foreign Trade said with a smile: "Director Gao, according to the agreement between us and our partner in the United States, we will probably meet several times every year in the future, haha."

Gao Zhendong laughed and joked with him, thinking that it wouldn't last for a few more years.

After finishing his work, it was almost time to get off work, so Gao Zhendong rode his bike home from the Ministry of Foreign Trade.

As soon as he entered the room, Gao Zhendong called Lou Xiao'e, who was busy, over and said, "Xiao'e, Xiao'e, come and see what good things I brought back."

Lou Xiao'e handed the teacup to Gao Zhendong and placed it in front of him: "What good stuff?"

Gao Zhendong looked like a money-grubber: "Money, I brought money back, hehe."

The amount of money is a bit large, so it's not easy to show off outside, but it's okay to show it off in front of your wife.

Lou Xiao'e smiled and said, "Yeah, good stuff, good stuff, got it."

From her words, she showed that she didn't take this matter seriously at all, and spoke in a perfunctory tone as if she was just treating a child, saying, "Well, money is not important. What's important is the interaction with Gao Zhendong."

——I don’t care whether my Zhendong is rich or not. He is not as rich as my family anyway.

As he spoke, he took the check, took one look at the amount, and was stunned.

"So many?" Although he wasn't too upset, he was still a little surprised.

"Well, I published a book abroad, and this is my royalty."

Lou Xiao'e felt relieved. She knew Gao Zhendong's ability to make money by writing books. Although the sales of these domestic books were not that high for each individual book, the total was still quite a lot.

But when she turned around, she was a little worried: "Zhendong, is it too much? It won't be a problem, right? Are we..."

Although naive, Lou Xiao'e is not stupid. Given her background, she naturally sees things more far-reaching than money.

Gao Zhendong shook his head: "It's okay, the higher-ups must know about it. It was the Ministry of Foreign Trade that notified me to collect the money."

Oh, it’s endorsed by a ministry. Lou Xiaoe finally felt relieved and was very happy. Her own Zhendong’s ability was really first-class. It had nothing to do with how much money he had. The important thing was that it proved that she had a good vision.

She looked at it carefully for a while, then handed the check back to Gao Zhendong: "Go to the bank and deposit it in your account some other day. This amount of money is too big to leave with me."

Gao Zhendong didn't say much, he just took it and kept it.
