Chapter 395

This......

What the hell is this?!

After reading the title of Gu Lu's article, the mathematician was completely confused.

What is this thing?

His mind was filled with this question.

He really couldn't understand the meaning of Gu Lu's question.

Because no matter how you look at this article, it doesn't look like the name of a math paper.

And GaN wide bandgap semiconductors?

This thing must be in the field of physics and materials science!

Suddenly appearing here, did you go to the wrong set?

The mathematician's mind was 10,000 capital letters.

It caused his brain to short-circuit for a long time.

It took nearly half a minute for the mathematician's brain to come back to its senses.

After that, the mathematician speculated on two possibilities.

One is that when Gu Lu uploaded the paper, he accidentally typed the wrong name of the topic.

The other is Gu Lu's article, which is a paper in the direction of mathematics and physics.

Two guesses, the latter will be slightly more likely.

Thinking that Gu Lu's article was very likely to be a paper in the direction of mathematical physics, the look in the mathematician's eyes was a little gloomy.

Because his main focus is in the field of number theory, not mathematical physics.

Even if Gu Lu's article would cover a certain branch in the field of thermal mathematical physics, he would not be able to participate in it.

While thinking like this, he clicked on Gu Lu's paper.

After all, he still decided to read this article by Gu Lu.

The mathematician was presented with a dozen pages of paper in PDF format.

At the top, the title of the paper still shows the one related to GaN wide tight band semiconductors.

The following line is a list of authors.

Among the four people, except for Gu Lu, the other three mathematicians did not know each other.

I've never even heard of a name.

"It should be Gu Lu's leader and his two assistants. ”

The mathematician didn't think much of it and read on.

The following is the text of the paper.

"Semiconductors must be doped with impurities to design new and improved properties. For example, GaN, which represents an extremely important semiconductor today, has a wide range of modern applications, including light-emitting diodes, laser diodes, and power electronics. The formation of optoelectronic devices by p-type and n-type GaN is ......"

As soon as he finished reading the first few lines, the mathematician began to realize that something was wrong.

But he chose to keep his doubts open for the time being, and read on.

“…… However, there is currently no direct experimental evidence to support the position of the carbon lattice in GaN, partly due to the lack of effective characterization methods. “

"However, I found that through infrared spectroscopy and Raman spectroscopy, it is possible to overcome the measurement problems caused by the strong residual ray band correlation reflection region in GaN, and through experiments, two local vibration modes related to C in semi-insulating GaN can be observed, and combined with first-principles calculations, the specific location of C impurities in the crystal lattice can be obtained!"

"Below, the specific process of the experiment......"

？？？

Reading this, the mathematician was once again blindsided.

It's not that it's good to be math and physics, why do you still do experiments?

Although the field of mathematical physics includes mathematics and physics, to be reasonable, this field is still dominated by mathematics and supplemented by physics.

To put it simply, it is to convert a physical problem into a mathematical language and then solve it mathematically.

But what about the article in front of you?

After reading the first page, the mathematician never saw a shadow of half-dime mathematics from beginning to end.

Totally unscientific!

But the mathematician was still not a believer.

He chose to read on!

But......

After two more pages, the mathematician couldn't read anymore.

It's not that he doesn't want to read it.

It's that he can't understand it at all.

It's full of a bunch of technical terms in the field of semiconductor physics.

For him as a mathematician, it was too hard for him to read.

I can't read it anymore.

But the mathematician has established one fact.

That's ......

This paper must not be a math article!

Because in the whole article, Gu Lu used a few lines of formulas in addition to using first-principles calculations on the last few pages of the paper.

Most of the rest of the article is devoted to physics experiments.

This is a standard semiconductor physics paper!

The mathematician was frightened by the conclusion he had reached.

He looked at the author's column of the two words Gu Lu, and thought about the conclusion he had reached, and was instantly shocked!

Today, in the world of mathematics, many people still debate whether the law is omnipotent in all fields.

But in the opinion of this mathematician.

There's no need to argue about this thing anymore.

Because Gu Lu has now jumped out of the world of mathematics and dabbled in the world of physics.

Gu Lu is marching towards the omnipotence of all disciplines!

In such a situation, it is very unnecessary to argue whether Gu Lu is omnipotent in all fields of mathematics.

The mathematician clicked on the cross in the upper right corner of the paper, ready to make the news known to more people, only to find that there were already many comments underneath the paper.

…………

"Sofa!"

"Bench!"

"It's a dead birthday, Gu Lu's boss actually cheated the corpse!"

"The tiger touches the big guy in front!"

"Can Big Guy Gu Lu PY, my ass is white!"

The first few floors are full of unnutritious reviews.

From the sixth floor, the comments started to normalize.

In other words, isn't Gu Lu cooperating with Simon to overcome the Hodge conjecture, how can he still have time to publish new articles, is it a previous manuscript. ”

"I ask weakly, can anyone tell me what the title of this article means, I don't understand. ”

"That's not easy...... Hey, I'm rubbing, what's this special meow!"

"I just clicked to roughly scan it and came back, and I tell you that one of my full professors at an Ivy League university didn't even understand the first three pages and retreated. ”

"Why? Is Professor Gu's article very profound?"

"No, because his article isn't a math paper at all. ”

Not a math paper?!

Everyone was stunned.

Then everyone began to notice the grouping of Gu Lu's article.

When authors upload papers on ArXiv, they will upload them in special groups according to different research directions.

At the end of the article, the specific grouping of the article will be marked.

And Gu Lu's article, the grouping shown is:

[Physics]: Semiconductor physics

Semiconductor Physics !!

The mathematicians who saw this group were all stunned.

Here's a ...... Physics Papers?!

Gu Lu, a mathematician, actually uploaded a paper on semiconductor physics!

Shocked, confused, unbelievable!

Many expressions appeared on everyone's faces.

Because they just can't believe it!
