Hearing him say this, everyone couldn't help but be excited.

Tang Xiu couldn't help but be surprised, this thing was really that good?

She thought it was just an ordinary thing!

In fact, graphene nanoribbons with a width of less than 10nm are definitely high-quality graphene nanoribbons, which are generally only possible to be manufactured by national research institutes, and once manufactured, it is definitely big news.

At present, there have been teams in China that have developed graphene nanoribbons with a width of less than 10nm.

Tang Ming and Gu Dechang are not experts in new materials, but they often read newspapers, plus they are quite sensitive to this conductive material, so they know a little.

And that's not all, they know that the material is extremely valuable.

Tang Ming and Gu Dechang held their breath and continued to observe for a while, and after coming to a conclusion in their hearts, they glanced at each other again, and their expressions became extremely solemn.

"Tang Xiu, did you really watch Dongzi make it by himself?" Tang Ming asked Tang Xiu again.

Tang Xiu was surprised, nodded and said, "Yes, Brother Dongzi bought a lot of things." Not only some filtration instruments, but also concentrated sulfuric acid, sodium nitrate, potassium permanganate, he made himself in the room. If you don't believe me, you can ask Brother Dongzi. ”

Hearing this, Tang Ming nodded, and turned his head to look at Gu Dechang.

Gu Dechang didn't speak, his face was solemn.

Tang Ming couldn't help it, so he shouted at Gu Dong's room: "Gu Dong, come out!"

Gu Dong didn't react as if he hadn't heard it.

"Gu Dong?" Tang Ming shouted again.

"I'm reading, I didn't hear!" a voice came from inside the room.

Tang Ming suddenly couldn't cry or laugh, this kid was still sulking, he turned back to Gu Dechang and said, "Dechang, I have to be cautious about this thing." If it's really graphene with a width of less than 10nm, it's gold, no, it's diamond!"

"I don't know much about graphene!" Gu Dechang said with a frown.

"Then find a laboratory to verify it first, this kind of thing is very troublesome to verify, you have to find a professional laboratory!" Tang Ming said.

Gu Dechang thought about it, was slightly silent, then stood up and said, "Let's go, go to his room and have a look!"

When Tang Ming saw it, he couldn't help but be happy, this old boy still couldn't pull his face, nodded and said, "It's okay to go and take a look, but you have to make three chapters of the law, don't get angry." Whether this thing is high-quality graphene nanoribbons or not, he can make it, which shows that he does have some ability, and this kind of thing must be encouraged, but not blindly scolded. ”

When Gu Dechang heard this, he smiled bitterly and said, "This kid must be busy with a lot of things for me. I don't want to interrogate him properly, and I don't know how he turned the sky upside down!"

"Haha, your old boy really can't be a good parent!" Tang Ming laughed, and immediately stood up and said, "Let's go, let's take a look." If it's really high-quality graphene, then it's a big deal!"

Although Gu Dechang didn't admit it, he nodded approvingly at this time.

He knows a little more about graphene than Tang Ming.

The two immediately walked towards Gu Dong's room with great interest.

And Gu Hao, Lu Li, Tang Xiu and the others glanced at each other and hurriedly followed.

There were a lot of things in Gu Dong's room, most of which he had just purchased, and some of the materials had been placed in a corner of the room by him.

When Dad and Tang Ming walked in, he was indeed lying on the bed reading a book, and when he saw them come in, he got up from the bed.

Gu Dechang couldn't pull his face to speak, while Tang Ming smiled at Gu Dong and asked, "Dongzi, come over and explain this thing." How did you get this thing? How did you come up with the idea of making batteries out of this thing?"

Gu Dong was originally a little angry, but looking at their appearance, he was slightly stunned, sighed and said, "I saw it when I watched the news." ”

He didn't say much, didn't seem to want to explain too much, and looked like he was lacking in interest.

"What you saw on the news?" Tang Ming was surprised.

Gu Dong nodded, and explained calmly: "This is produced by mixing concentrated sulfuric acid and potassium permanganate, and peeling it with cutting carbon nanotubes, the technical content is not high, and its overall structure is a single-layer two-dimensional honeycomb lattice structure. ”

"The technical content is not high? What does this mean?" Tang Ming was surprised and stared at him: "Could it be that you can make something better?"

Gu Dong shrugged: "Without equipment, you can't do it!"

Tang Ming immediately glanced at Gu Dechang.

Gu Dechang still didn't speak.

Tang Ming was a little speechless, knowing that the two fathers and sons were fighting, he couldn't help but feel funny in his heart, and said: "I just heard you say that you are planning to use this graphene nanoribbon to make batteries? As far as I know, this kind of thing can indeed make batteries, but now it is only theoretical." You asked your dad for so much money, are you sure you can make it?"

"I'm not sure!" Gu Dong naturally didn't say anything, but said: "But I only know that I can't lose." Even if I can't make a real battery, I can still make this material. I know that it can definitely be sold for money! If the quality is better, up to about 3nm, the price will be more expensive!"

"Simply reducing the width doesn't mean anything!" Tang Ming said.

"This really doesn't mean anything, but I can be sure that the carrier mobility of my material is definitely much higher than that of most of the world!" Gu Dong nodded and said: "Moreover, I use a new method, use the simplest technology to obtain the highest quality material, and most importantly, if the conditions permit, I can mass produce!"

When Tang Ming and Gu Dechang heard this, their whole bodies were shocked.

As electrical engineers, they know best what carrier mobility is.

Carrier mobility, also known as electron mobility, is a physical quantity used in solid-state physics to describe how fast or slow electrons inside a metal or semiconductor move under the action of an electric field.

At the same electric field strength, the greater the carrier mobility and the faster the movement, the better the quality of the semiconductor.

This is an important parameter to measure the conductivity of semiconductors.

Tang Ming held his breath and asked, "What do you think is the carrier mobility of your material?"

Gu Dong frowned and said, "I haven't been rigorously tested, but with the performance of this material, there is no problem with reaching 8000 cm2/Vs." ”

"8000 cm2/VS? are you sure?" Tang Ming couldn't help but exclaim when he heard this.

You must know that the current electron mobility of semiconductor silicon materials is only one or two thousand cm2/Vs, and silicon materials can be regarded as semiconductor materials with excellent performance.

If it can reach 8000 cm2/Vs, it is definitely a great performance.

Gu Dong shrugged: "In fact, really high-quality graphene nanoribbons can reach more than 21,000 cm2/Vs, and this is just an intermediate quality." Uncle Tang, have you heard about the properties of real graphene nanomaterials?"

Tang Ming had naturally heard of it, and he also knew the magic of this material, but now that he heard Gu Dong say this, he still couldn't believe it.
