Chapter 250： : Far more than graphene technology! Seek full set!

Black scale material is good.

But to be used with semiconductor crystals.

Current hedging can easily occur.

Causes the crystal to crack.

The chip is damaged.

At present, the black scale two-dimensional material has just been produced. Everyone cannot see these shortcomings, and even this hedge disorder can only occur to a certain extent.

Especially in summer.

The mobile phone has a large load and a heat wave inside the mobile phone will most likely cause the current hedging problem.

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

He has the black scale material technology, why did he not make it, because the black scale material has been shown in his memory and cannot be used on mobile phones.

The IOS Group has boldly applied the black scale material to mobile phones.

Black scale technology.

Nominations have been made internationally.

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

It's just that there has been no progress.

They use black scales, and it seems that they have been forced to do so by themselves.

Ye Fan laughed.

Release Blackscale.

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

Take time to test your phone.

Black scales will have current hedging. Ye Fan is 100% guaranteed.

So there is no worry at all.

At the moment, IOS Group headquarters.

A large group of journalists have gathered.

The news of Black Scale made them all quite excited.

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

Hit by a small sky company.

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

Can rise again today.

This makes 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 press conference has begun.

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

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

"Dear journalist friends, everyone, after a month!"

"We at IOS Group have made a lot of rectifications and modifications, and now we have developed black scale material technology!"

"Look at this, this black scale material on my hand!"

All reporters immediately looked at the black scale crystals held by the figure.

Taking pictures one by one crazy.

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

Two-dimensional crystals are nanometer-thick planar crystals made by stacking several monoatomic layers, such as the well-known graphene, but graphene has no semiconductor band gap, that is, it separates the electronic conductive energy band (conduction band) from the non-conductive energy band ( Valence band), which means that it is difficult to complete the conversion between the conductor and the insulator, and it is not possible to achieve the logical opening and closing of digital circuits. Black phosphorus, which is also formed by stacking monoatomic layers, has a semiconductor band gap. "

Wow.

The reporters at the scene boiled instantly.

"Excuse me, does graphene have conductivity, hasn't it already been said by Future Technology Crystal Co., which has strong conductivity!"

"This reporter friend, the conductance you are talking about is totally two-level technology with the conductance I am talking about, please don't confuse!" Said the image man with a smile.

Oao.

The reporters were aggressive.

Is it different?

It's all a name.

Is it different?

"In technology, now that we have made black phosphorus into a two-dimensional crystal with nanometer thickness, we find that it has very good semiconductor properties, so that we can make a perfect replacement on the K11 mobile phone model!"

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

In addition to its superior electrical properties, the optical properties of black phosphorus also have huge advantages over other materials including silicon and molybdenum sulfide. Its semiconductor bandgap is a direct bandgap, that is, the bottom of the electronic conductive energy band (the conduction band) and the top of the non-conductive energy band (the valence band) are at the same position. However, traditional silicon or molybdenum sulfide are indirect band gaps, which require not only energy (band change), but also momentum (position change).

This means that black phosphorus and light can be directly coupled. This feature makes black phosphorus an alternative material for future optoelectronic devices (such as photoelectric sensors), which can detect the entire visible light to near-infrared spectrum. "

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

Wow.

The scene was boiling again.

Uproar.

"It's 10,000 times that of graphene. This black scale is too bad, right?"

"Isn't it? If it's 10,000 times more powerful than graphene, wouldn't it be 10,000 times better?"

"Well, I think the X mobile phone is already enough for the sky. I didn't expect that the IOS Group would make it even for the sky!"

The reporters at the scene were rumbling.

Various discussions boiled.

There was a smile on everyone's face.

One by one, extremely excited.

"Excuse me, future technology crystal companies have holographic projection technology in their hands. If they use this technology on mobile phones, how will the IOS Group take action?"

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

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

The reporters raised their hands and asked loudly.

Watching these reporters so excited.

The man with a smile on his mouth said, "Everyone, your questions come one by one!"

"First I answer the gentleman's question now!"

"You said that the future technology crystal company has mastered the holographic projection technology? Can it be implanted in the mobile phone? According to our investigation and understanding, the future technology crystal company does not have a substantial grasp of the holographic projection technology, and the founder Ye Fan is in the technology The technical issues discussed at the discussion meeting ~ www.novelhall.com ~ are just concepts and ideas. As far as we know, the technology of holographic projection has not yet been produced! "

Reporters heard this answer.

Each one widened his eyes.

This..

This is breaking news.

"Do you have evidence?"

Among the crowd, a dynasty reporter shouted with a somber expression.

"Evidence? What kind of evidence is needed? If you want evidence, Professor Wu Gaofei, a future technology crystallization company, will change jobs and tell us these things.

Wow.

The scene can no longer be calm.
