Chapter 378: Graphene Chip (for Alliance Leader Hao Ayouhe)
Airplanes!
When the power was turned on, the entire huge production line suddenly emitted a violent humming sound, and the entire workshop floor began to tremble regularly. Pen | fun | pavilion www. biquge。 info
After a few moments, the humming sound was still there, but the amplitude of the ground shaking had become small, and after a while, it was almost gone.
Six small robots have a clear division of labor, three of which overhaul and operate the production line equipment, and the other three quickly transport graphite materials and substrate materials to the designated location in the workshop.
It is worth mentioning that although the equipment in the first part of the production line can process non-graphite substances such as wood and then synthesize graphite, the efficiency is very average like that of the pillow production line, which can synthesize pillow cores.
Therefore, it is still necessary to transport the ready-made graphite from the outside and throw it into the first part of the equipment for re-forging, so that the production speed will be increased several times to ensure that the maximum daily output is achieved.
After forging, the graphite is laser washed, and then the nanofabrication of graphene begins.
Of course, the most common CVD manufacturing method in the world's laboratories does not require graphite ore, because that method uses methane or other gases to grow graphene on copper foil, which is the so-called vapor deposition method.
The production of this kind of graphene film is actually to pass the gas through a series of treatments, especially high temperature treatment, so that it grows on the metal substrate until it is overgrown on the metal substrate.
Basically, the raw materials used in the CVD manufacturing method are mostly methane, not graphite.
From the perspective of the selection of raw materials, the production line produced by the Science and Technology City needs graphite, and with the support of strong nanotechnology, it can prepare real single-layer, double-layer or few-layer graphene, with large output and easy peeling.
The CVD manufacturing method can also prepare the corresponding graphene, and the yield is currently uncertain, but the peeling method is more complicated.
In general, compared with the Science and Technology City, the difference in technology is still too great.
With a turbulent and fluctuating heart, Su Cheng pulled over a bench and sat in the workshop, watching the work of the small worker robot with blazing eyes.
Half an hour later.
"Boss, the first batch of graphene is out, do you want to take a look?"
Su Cheng's old god was there, his eyes were open, but his mind was already drifting away, and when he heard the shout of a small worker robot, he moved his eyes and came back to his senses.
"The first batch of graphene is ready?" Su Cheng stood up.
"That's it!"
The forging of graphene is in batches, and it takes half an hour for graphite ore to be thrown into the production line equipment to be baked.
Coming to the tail of the fourth part of the equipment, Su Cheng blinked when he saw the large pile of transparent chips soaked in water.
"This is graphene?" Su Cheng reached out to pick one up.
"Boss, I'm coming!" a small worker robot quickly grabbed in front of him, took the initiative to pick up a graphene wafer for him, and then respectfully handed it to her.
Holding the graphene wafer as clear as a drop of water in his hand, Su Cheng blinked and looked at it, this graphene wafer was the size of a palm, about 10cm square, and the thickness was 0.1mm.
Of course, don't look at the thickness of this graphene wafer is 0.1mm, but this is not a graphene wafer composed of many layers of graphene.
Suppose that this is really a wafer with multiple layers of graphene stacked continuously, then it is not a two-dimensional material, but a three-dimensional material, and the graphene will not be transparent, but will be pitch black.
Because the thickness of a single layer of graphene is only 0.35 nanometers, it is too small, and once superimposed, it will produce the interaction force between molecules, which will lead to the weakening or even disappearance of graphene.
However, the graphene wafer in Su Cheng's hand is a single-layer structure of graphene.
As for why it is so thick, it is mainly because the substrate embedded with graphene, according to the structure of a layer of substrate and a single layer of graphene, so a graphene wafer of such a thickness is obtained.
In addition, it is worth mentioning that the graphene films on the market now only have a surface, which is far from the extent that this graphene is inter-mosaic substrate from the nano level, mainly because the technology is not so advanced.
Su Cheng was fiddling with the graphene, and wondered: "Didn't you say that graphene is soft, how can this one in my hand be hard?"
When this small worker robot heard this, he stood in place in a daze, Su Cheng's words made him at a loss and unable to answer, mainly because he was only responsible for tail work, and he didn't know the specific principle.
Calling out the system, Su Cheng expressed his doubts again.
The system gave him a clear answer this time.
"Host, when I was producing just now, the substrate material was quartz, so now the graphene in your hand is a quartz substrate, or silica substrate, which can be used to make computer CPUs. ”
"Graphene is not a semiconductor in the strict sense of the word, because the conductivity of a single layer of graphene is uncontrollable. ”
"Quartz, as a substrate material, can allow graphene and silica to produce van der Waals forces, which will make graphene wafers have super semiconductor properties at the molecular level. ”
"Of course, the most powerful substrate for semiconductors is silicon, but in this case, the graphene wafer cannot be transparent. ”
Su Cheng was stunned when he heard this, and he was unaware of the system's explanation.
After a pause, the system continued: "Host, do you want to make a powerful ultra-micro transistor?"
"Do you want to make a super microprocessor?"
Su Cheng just wanted to speak, but the system rushed ahead of him again: "Do you want to have a powerful quantum computer?"
"Damn, I want to, but what do you want to say?" Su Cheng frowned.
"If you want to, please hurry up and do the task, and then go crazy and draw the lottery. ”
When the words fell, when Su Cheng shouted again, the system had disappeared without a trace, and Su Cheng had long been used to it, and after muttering a word, he withdrew from the system space.
Playing with the graphene chip in his hand, he muttered, "Can this thing make ultra-micro transistors?" ”
"But...... It's okay to sell it to someone else. ”
Thinking of this, Su Cheng frowned: "No, the current computer technology is too developed, if you sell it like this, the CPU market will definitely be occupied in a short period of time, huh...... It's better to eat alone. ”
Su Cheng felt that if he sold the quartz-based graphene wafers to those computer companies, they would be able to make ultra-micro transistors, and then design powerful mobile phones or computers.
"But...... The system prompted that if you want to get the technology, you have to do a task lottery, is it difficult to become an advanced lottery area, there is a surprise?"
It has only been a little more than a week since the system was upgraded to an advanced state, and Su Cheng has not dared to use the task points to draw a lottery because he is concerned about the graphene production line.
However, now that the first graphene production line has been formed, after reserving the task points required for the plant battery production line, you can try it by lottery.
"We'll talk about it later!"
As soon as he thought of this, Su Cheng set his eyes on the graphene wafers soaked in the water again, thought about it, and reached out to grab some of them, all of which were palm-sized wafers.
"How much graphene is there here?"
"25 kilograms of single-layer graphene and one ton of integral graphene wafers. A small worker replied.
Su Cheng compared, so calculated, the specific gravity of a single layer of graphene and quartz substrate should be 1:30.
25 kilograms of single-layer graphene in half an hour, and the working time of the small worker robot is about 20 hours a day, so that it can produce exactly 1 ton of graphene.
Of course, the mass of the overall graphene wafer is 40 tons.
