The black scale material is good.

But it has to be applied to semiconductor crystals.

Current hedging can easily occur.

Causes crystals to crack.

The chip is damaged.

At present, the black scale two-dimensional material has just been made, and everyone can't see these shortcomings, and even the hedging disorder will only occur to a certain extent when used.

Especially in the summer.

The load of the mobile phone is large, and there is a heat wave in the mobile phone, which is the most likely to cause the problem of current hedging.

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 indicated that the black scale material cannot be used on the mobile phone.

However, IOS Group has the audacity to use black scale materials on mobile phones.

Black Scale Technique.

There were nominations as early as the international community.

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 by themselves to have no way out.

Ye Fan smiled.

Publish Black Scales, just release it.

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

Take the time to test your phones.

The black scales will have an electric current hedge, and Ye Fan is 100% guaranteed.

So there was no worry at all.

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

A large group of journalists has gathered.

The news of Black Scales made them all quite excited.

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

Knocked down by a small Celestial Empire company.

It's something that all of them don't want to see.

Now it can rise again.

It made them very excited and happy.

"I can get in, I can get in!"

Journalists shouted.

Everyone rushed in.

Downstairs from the IOS Group headquarters.

A small launch event has begun.

The group's promotion image person is standing on the stage with a smile on his face, looking at everyone smiling.

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

"Hello journalists, it's been a month!"

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

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

All the reporters immediately looked at the black-scaled crystal in the figure man's hand.

One by one, they frantically took pictures.

The corner of the image person's mouth smiled: "In recent years, two-dimensional crystal materials have become a new direction in semiconductor materials research because of their superior electrical properties. We all know that the future technology crystallization company has researched graphene, and even won most of the mobile phone market in the Celestial Empire in one fell swoop, everyone thinks that our IOS group is about to end, but in fact, during this time, the laboratory staff worked overtime day and night, and finally successfully developed a new two-dimensional semiconductor material - black phosphorus, and successfully prepared the corresponding field-effect transistor device, which will have the potential to replace the traditional silicon and become the basic material for electronic circuits.

Two-dimensional crystals are nano-thick planar crystals stacked by several layers of single atomic layers, such as the famous graphene, but graphene does not have a semiconductor band gap, that is, it separates the no-man's forbidden area between the conductive energy band (conduction band) and the non-conductive energy band (valence band) of electrons, that is to say, it is difficult to complete the conversion between conductors and insulators, and cannot realize the logical opening and closing of digital circuits. Black phosphorus, which is also made up of stacked layers of single atoms, has a semiconductor band gap. ”

Wow.

The reporters at the scene instantly boiled.

"Excuse me, whether graphene has conductivity properties, hasn't Future Technology Crystallization Company already said that the conductivity performance is very strong!"

"This journalist friend, the conductance performance you are talking about and the electronic conductance I am talking about are completely two levels of technology, please don't confuse it!" The image man said with a smile.

O'O.

The reporters looked confused.

Isn't it the same?

It's all the same name.

Why is it different?

"In terms of technology, now we have made black phosphorus into a nano-thick two-dimensional crystal, and found 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 black phosphorus two-dimensional crystal has a good electron mobility (~1000cm2/Vs) and a very high leakage current modulation rate (10,000 times that of graphene), which is similar to the traditional material silicon for electronic circuits.

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

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

"Of course, these preliminary research results are far from reaching the limit of black phosphorus performance, 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, this black scale is too rebellious, right?"

"Isn't it, if it is really 10,000 times more powerful than graphene, wouldn't the performance of the mobile phone produced be 10,000 times?"

"Tut-tut, I think the X phone is enough against the sky, but I didn't expect the IOS group to make it even more against the sky!"

The reporters at the scene were in a clamor and boiling.

All kinds of discussions boiled.

There were smiles on everyone's faces.

One by one, they were extremely excited.

"May I ask, if the future technology crystallization company has holographic projection technology in their hands, if they use this technology on mobile phones, how will IOS Group take action?"

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

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

One by one, the reporters raised their hands and asked loudly.

Seeing this group of reporters so excited.

The figure smiled at the corner of his mouth and said, "Everyone, your questions come one by one!" ”

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

"You said that the future technology crystallization company has holographic projection technology? Can it be implanted in a mobile phone? This problem, according to our investigation and understanding, the future technology crystallization company did not have a substantial grasp of holographic projection technology, and the founder Ye Fan talked about the technical aspects of the technical seminar, that is just a concept and idea, as far as we know, holographic projection technology, has not yet been able to produce it! ”

Journalists heard this answer.

Their eyes widened.

This..

That's big news.

"Do you have proof?"

In the crowd, a Celestial Dynasty reporter roared with a gloomy face.

"Evidence? What evidence is needed for this? If you want evidence, Professor Wu Gaofei of the future technology crystallization company jumped ship and told us these things, is it considered evidence? ”

Wow.

The scene could no longer be calm.

....
