Hearing that he said this, everyone was so excited.

Tang Xiu couldn't help but be surprised. Is this thing 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. These nanoribbons can generally be manufactured only by national research institutes, and once they are manufactured, it is definitely big news.

At present, a team in China has 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. In addition, they are very sensitive to this conductive material, so they only know something.

Not only these, they also know that this material is of great value.

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

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

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

When Tang Ming heard this, he nodded and turned to look at Gu Dechang.

Gu Dechang didn't say anything, his face was solemn.

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

But Gu Dong didn't seem to hear it and did not respond.

"Gu Dong?" Tang Ming shouted again.

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

Tang Ming was so amused that the boy was still sulking. He turned to Gu Dechang and said, "Dechang, I guess this thing must be cautious. If you can't do it well, it's really a high-quality graphene nanoribbon. I don't know what he has developed? If it's really graphene with a width of less than 10nm, it's simply gold, no, it's simply 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 for a while, was slightly silent, then stood up and said, "Go and go to his room and take a look!"

Tang Ming couldn't help but be happy when he saw this. The old guy couldn't hold his face down. Nodded and said, "It's OK to go and see, but you have to make three rules, don't get angry. Whether this thing is a high-quality graphene nanoribbon or not, he can make it, which means he is really capable. Such things need to be encouraged, and you can't just beat and scold them."

Gu Dechang heard this and said with a wry smile: "This kid must be busy with a lot of things. He also adds graphene nanobelts! If I don't interrogate it carefully, I don't know how he is going to make a fuss!"

"Haha, you really can't be a good parent!" Tang Ming laughed and stood up and said, "Let's go and have a look. If it's really high-quality graphene, then you'll make a fortune!"

Although Gu Dechang did not admit it, he nodded in agreement at this time.

He knows more about graphene than Tang Ming.

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

Gu Hao, Lu Li, Tang Xiu and others looked at each other and hurriedly followed.

There are many things in Gu Dong's room, most of which were bought by him, and some of the materials were placed in a corner of the room.

When his father and Tang Ming walked in, he was indeed lying on the bed reading. When he saw them coming in, he got up from the bed.

Gu Dechang couldn't speak, while Tang Ming asked Gu Dong with a smile: "Dongzi, come and explain this thing. How did this thing come up? How did you think of using this thing to make a battery?"

Gu Dong was a little angry at first, but when he looked at them, he was slightly stunned and sighed and said, "I saw it after the news."

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

"What did you see when you read 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 off the cut carbon nanotubes. The technical content is not high. 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: "Can you still do better?"

Gu Dong shrugged: "No equipment can be done!"

Tang Ming immediately glanced at Gu Dechang.

Gu Dechang still didn't speak.

Tang Ming was speechless. He knew that the father and son were fighting, and couldn't help but feel funny in his heart and said, "I just heard you say 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 theoretically possible. If you ask your father to ask for so much money, are you sure you can make them?"

"I'm not sure!" Gu Dong naturally wouldn't say enough, just said: "But I only know that I can't lose money. 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 and reaches about 3nm, the price will be more expensive!"

"Simply reducing the width does not mean anything!" Tang Ming said.

"This does not mean anything, but I can be sure that the carrier mobility of the material like me is definitely much higher than most of the world at present!" Gu Dong nodded and said: "And I am using a new method to obtain the highest quality materials with the simplest technology. The most important thing is that if conditions permit, I can mass-produce it!"

When Tang Ming and Gu Dechang heard this, their whole body was shocked.

As an electrical engineer, they know the best about what carrier mobility is.

Carrier mobility, also known as electron mobility, is a physical quantity used in solid physics to describe the speed and degree of movement of electrons inside metals or semiconductors under the action of electric fields.

Under the same electric field intensity, the greater the carrier mobility and faster the movement, which means the better the quality of the semiconductor.

This is an important parameter for measuring 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 have not undergone rigorous testing, 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 exclaimed when he heard this.

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

If it can reach 8000 cm2/Vs, it will definitely be considered excellent performance.

Gu Dong shrugged: "In fact, a truly high-quality graphene nanoribbon can reach more than 21,000 cm2/Vs. I am just an intermediate quality. Uncle Tang, have you heard of the properties of real graphene nanomaterials?"
