Chapter 397

At night.

Gu Lu took Simon over to eat.

Director Zhang's place of hospitality is the Yanwei Building near Yanda.

Report the name of Director Zhang.

The waiter in a cheongsam took Gu Lu all the way to the private room on the third floor.

"Hahaha, Gu Lu, I can be regarded as waiting for you!"

The door to the private room is open.

When Director Zhang saw Gu Lu, he greeted him with a smile and gave Gu Lu a big bear hug.

Inside a private room.

In addition to Director Zhang, Professor Fang and Professor Song are also there.

Gu Lu nodded to the two professors.

The two professors responded with a polite smile.

Director Zhang looked at Simon who was standing beside Gu Lu.

Go without saying.

Director Zhang guessed Simon's identity.

"This must be Professor Simon of the University of Bonn, hello, my name is Zhang Weiguo. Director Zhang politely stretched out his right hand.

Simon shook hands with Director Zhang and spoke in fairly fluent Chinese, "Hello, I'm Simon." ”

I spent more than two months in China.

Simon is already proficient in some of the more commonly used Chinese.

And that's when Simon didn't concentrate on his studies.

Director Zhang politely invited Gu Lu and Simon to sit down.

"The dishes are almost ready, what else do you need to order?"

Eight or nine dishes were already on the table.

This was to save time, and it had been ordered before Gu Lu and the others came.

Director Zhang asked the waiter to hand the menu to Gu Lu to see if he wanted to add anything.

Gu Lu briefly glanced at the menu, and then glanced at Simon, whose eyes glanced at the dinner table from time to time.

"You don't have stinky tofu and preserved eggs here?" Gu Lu asked.

"Uh...... No. The waiter was stunned for a moment, "But if you want to eat, you can ask the chef in the back to cook it." ”

"Okay, then add a copy of this, my foreign friend is just like this!" Gu Lu pointed at Simon.

Simon looked up inexplicably.

"Don't you need to add anything more?" Director Zhang asked when he saw Gu Lu put down the menu.

Gu Lu shook his head and smiled lightly, "These dishes are enough, but Simon likes the dish of stinky tofu and preserved eggs very much, so he added such a dish, I hope Director Zhang doesn't mind." ”

"Don't mind, don't mind. Director Zhang waved his hand again and again, pulling the corners of his mouth, "It's just that Professor Simon's taste preference is really unique!"

Stinky tofu and preserved eggs, that is the existence of most Chinese people.

I didn't expect this foreign friend to prefer this.

The taste is just too peculiar.

The dishes are ready in no time.

Including Simon's plate of stinky tofu scrambled preserved eggs.

A private room is a confined space.

The smell of stinky tofu spreads through.

The taste is indeed quite sour.

Gu Lu looked at the table full of big fish and meat, and he didn't have much appetite.

But Simon was a delightful eater.

A bite of stinky tofu goes down the stomach.

Looking at the comfortable expression on his face, Gu Lu almost thought that he was going to moan.

Since they didn't have much appetite, Gu Lu and Director Zhang took a sip of tea and chatted.

Director Zhang talked about the paper, "Hey, Gu Lu, why did you add the names of the three of us in the first place!

Gu Lu picked up the teacup, took a sip of tea, and smiled lightly, "Now that the paper has been submitted, and the Physical Review Express has officially included it, it shouldn't be changed, Director Zhang, you just accept this reality." ”

"Besides, it's not a big deal!"

Isn't that a big deal?

Gu Lu's operation, to a certain extent, can be said to have rewritten the life trajectory of the three of them.

With the blessing of this paper.

The three of them will go a lot smoothly in their careers and in their follow-up scientific research work.

Seeing that Gu Lu looked like he took it for granted, Director Zhang didn't know where to spit it out.

After a deep sigh, Director Zhang no longer bothered with Gu Lu on this topic.

Gift.

They must be indebted.

And there is a lot to be owed.

This favor will be repaid in the future.

"Director Zhang, let's not mention this matter, my ears are about to come out of the cocoon, anyway, the matter is already a foregone conclusion, you can just accept it calmly!" Gu Lu waved his hand and said in a casual tone.

"Okay, don't mention it, don't mention it. Director Zhang nodded with a smile.

"That's right. Gu Lu suddenly thought of something and asked, "Director Zhang, is the current situation of the third-generation wide bandgap semiconductor industry difficult?"

This is a question that Gu Lu has always wondered.

Regarding the current international wide bandgap semiconductor industry, Gu Lu knows very little.

"It's not tough. After a few seconds of silence, Director Zhang slowly replied, "The prospects of this industry are still very optimistic, but there are a series of problems at present. ”

"One problem is the problem of the industry itself, that is, there are many technical problems that have not been solved, which will always cause various problems in practical application and cannot be realized for civilian use. ”

"The other is the issue of cost. The price of wide bandgap semiconductor raw materials is not too high, but compared with the first and second generation semiconductor materials, it is more expensive, and due to the immaturity of the technology, the wear rate is extremely high, resulting in a significant increase in costs. Therefore, although the performance of the products produced by wide bandgap semiconductors is better, the price will be much higher!"

"There is still a long way to go before it becomes truly civilian, and it will take at least four or five years to go. ”

Speaking of this, Director Zhang sighed softly.

Gu Lu nodded after hearing this.

One is technology and the other is price.

These are two of the current problems in the field of third-generation wide bandgap semiconductors.

But in Gu Lu's opinion.

It's all about technology.

As long as the technology is reached, it is possible to reduce losses in the production of wide bandgap semiconductors.

Naturally, the price can be greatly reduced.

Director Zhang then spoke, "The semiconductor research center here is now mainly developing lasers and detectors for wide bandgap semiconductors. ”

This is an industry with considerable potential.

Although the current market space for wide bandgap semiconductor lasers and detectors is only valued at $200 million by major authorities.

But Director Zhang doesn't think so at all.

"GaN-based ultraviolet detectors can complete the complex work of missile early warning, satellite secret communication, various environmental monitoring, and chemical and biological detection!

Director Zhang's tone was slightly excited.

"In the field of projection display such as micro projection and laser 3D projection, GaN laser has a huge market!

"In addition to that, there is also the area of lighting. The laser illumination technology based on the extension of the third-generation wide tight band semiconductor is very likely to lead the next industrial revolution in the field of lighting!"
