Billion Technology Crystal System

The black scale material is good.

But it should be used with semiconductor crystals.

Current hedging can easily occur.

cause the crystal to break.

Chip is damaged.

At present, the black scale two-dimensional material has just been produced, and everyone can't see these shortcomings, and even the hedging disorder will only occur after a certain degree of use.

Especially in summer.

The mobile phone is under heavy load, and there is a heat wave in the mobile phone, which is most likely to cause current hedging problems.

So this is the problem that Ye Fan has always been different.

He has the black scale material technology, why didn't he make it, because his memory has shown that the black scale material cannot be used on mobile phones.

However, the IOS Group boldly used the black scale material on the mobile phone.

Black scale technology.

There have been nominations already internationally.

It has even become a research project of major mobile phone groups.

But there has been no progress.

They use black scales, and it seems that they are forced to do this because they have nowhere to go.

Ye Fan laughed.

Release the black scale and release it.

If you want to occupy the market, you occupy it.

Test your phone with time.

Ye Fan is 100% guaranteed that the black scale will have current hedging.

So no worries at all.

And at the moment at the door of the IOS Group headquarters.

A large group of journalists had already gathered.

The news of black scales,

Get them all pretty excited.

You must know that IOS Group has always been a well-known brand in the world.

He was beaten down by a small Chinese company.

It's something they all don't want to see.

Now it can rise again.

It made them very excited and happy.

"I can go in, I can go in!"

The reporters shouted.

Everyone rushed in.

Downstairs at the IOS Group headquarters.

A small launch has been launched.

The group promotion image person is standing on the stage with a smile on his face, watching everyone smiling.

All the reporters at the scene raised their hands and wanted to ask questions.

"Hello, friends from the press, it's been a month!"

"Our IOS Group has made a lot of rectification and modification, and now we have developed the black scale material technology!"

"Everyone, please look at this black scale material in my hand!"

All the reporters immediately looked at the black scale crystal held in the figure's hand.

Taking pictures one by one like crazy.

The image person smiled and said: "? In recent years, two-dimensional crystal materials have become a new direction of semiconductor material research because of their superior electrical properties. We all know that the future technology crystal company has researched graphene, and even won the Chinese mobile phone in one fell swoop. In most markets, everyone thinks that our IOS Group is about to end, but in fact, during this period of time, our laboratory staff worked overtime day and night, and finally successfully developed a new type of two-dimensional semiconductor material - black phosphorus, and The corresponding field effect transistor device has been successfully prepared, and it will be possible to replace the traditional silicon and become the basic material of electronic circuits.

A two-dimensional crystal is a nanometer-thick planar crystal formed by stacking several monoatomic layers, such as the famous graphene, but graphene has no semiconductor band gap, which separates the electronically conductive energy band (conduction band) and the non-conductive energy band ( In other words, it is difficult to complete the conversion between conductors and insulators, and it cannot realize the logical on and off of digital circuits. Black phosphorus, which is also stacked by a single atomic layer, has a semiconductor band gap. "

Wow.

The reporters at the scene were instantly boiling.

"Excuse me, does graphene have electrical conductivity? Hasn't the Future Technology Crystallization Company already said that the electrical conductivity is very strong!"

"This reporter friend, what you said about electrical conductivity and what I said about electronic conductivity are completely two levels of technology, please don't confuse it!" The image person said with a smile.

Ooo.

The reporters were dumbfounded.

Is it different?

It's all one name.

Why is it different?

"Technically, now we have made black phosphorus into a nanometer-thick two-dimensional crystal and found that it has very good semiconductor properties, so that it can be a perfect replacement for the K11 mobile phone model!"

"In addition, our laboratory staff found that black phosphorus two-dimensional crystals have good electron mobility (~1000cm2/Vs), and a very high leakage current modulation rate (10,000 times that of graphene), which is comparable to that of electronic circuits. The traditional material silicon is similar.

In addition to its superior electrical properties, the optical properties of black phosphorus also offer huge advantages over other materials including silicon and molybdenum sulfide. Its semiconductor band gap is a direct band gap, that is, the bottom of the electron conducting energy band (conduction band) and the top of the non-conducting energy band (valence band) are at the same position, to achieve from non-conducting to conducting, electrons only need to absorb energy (light energy) , while traditional silicon or molybdenum sulfide are indirect band gaps, which require not only energy (energy band change), but also momentum (position change).

This means that black phosphorus and light can be directly coupled, a property that makes black phosphorus a candidate material for future optoelectronic devices, such as photosensors, that can detect the entire spectrum from the visible to the near-infrared region. "

"Of course, these preliminary research results are far from the limit of the performance of black phosphorus, and there is still great room for expansion."

Wow.

The scene was boiling again.

There was an uproar.

"It's 10,000 times that of graphene, isn't this black scale too heaven-defying?"

"Isn't it? If it is really 10,000 times stronger than graphene, wouldn't the performance of the mobile phone be 10,000 times as good?"

"Tsk tsk tsk, I think the X mobile phone is enough to defy the sky, but I didn't expect that the one produced by the IOS group would go against the sky!"

The reporters at the scene were boisterous.

All kinds of discussions boil over.

All had smiles on their faces.

One by one was extremely excited.

"Excuse me, Future Technology Crystal Company has holographic projection technology. If they use this technology on mobile phones, how will IOS Group take action?"

"Can the black scale material be used on other materials?"

"Will your company enter the automotive industry with graphene materials?"

The reporters raised their hands one by one and asked loudly.

Seeing this group of reporters so excited.

The image man said with a smile: "Everyone, come to your questions one by one!"

"First of all I will now answer this gentleman's question!"

"You said that the future technology crystal company has mastered holographic projection technology? Can it be implanted in mobile phones? According to our investigation and understanding, the future technology crystal company has not substantially mastered holographic projection technology, and the founder Ye Fan is in technology. The technical issues discussed at the meeting are just concepts and ideas, as far as we know, the technology of holographic projection has not yet been produced!"

The reporters heard the answer.

Everyone's eyes widened.

This..

This is breaking news.

"Do you have evidence?"

In the crowd, a Chinese reporter roared gloomily.

"Evidence? What kind of evidence is needed for this? If evidence is needed, Professor Wu Gaofei from the Future Technology Crystallization Company quit his job and told us these things. Is it considered evidence?"

Wow.

The scene could no longer be calm.
