But it is difficult to manufacture.
Compared with silicon-based chips, the manufacturing difficulty of carbon-based chips is not twice or twice as high at the current level of technology.
Whether it is the neat and stable ordering of carbon nanotubes, the control of the purity of carbon semiconductors, or the purification of carbon nanotubes, they are all huge problems.
Therefore, in comparison, silicon-based chips with lower technical requirements were undoubtedly the mainstream choice for R&D at that time.
Of course, on the other hand, path dependency is also a very important reason.
In the past few decades, semiconductor technology, especially integrated circuit manufacturing technology, has been based on silicon-based products.
During this period, the entire world has invested, and is still investing, countless manpower and funds in technological improvements.
No one would be willing to change tracks at this time unless there are dozens of times the advantage.
Although carbon-based chips are indeed superior, to be honest, they cannot achieve dozens of times the advantages of silicon-based chips.
Therefore, carbon was an abandoned material in the chip field in the past era.
It's just that this kind of abandonment is different from other materials, such as germanium crystals.
These germanium crystals have defects and their performance is not as good as silicon and were abandoned.
Carbon transistors, on the other hand, were abandoned due to the high technical difficulty of research and development.

In the laboratory, after discussing the test experimental data of the field emission scanning electron microscope, Xu Chuan returned to his office with the test experimental data of the field emission scanning electron microscope.
"Siyi, is Academician Chang Huaxiang now at the institute or at the Xia Shu base?"
When passing by the assistant room, he asked the assistant Shen Yi who was sorting the documents in his hand.
"Academician Chang is currently in charge of the lunar surface project at Xia Shu Space Base. Do you need me to contact him?" Shen Yi quickly replied.
"No, I'll just give him a call."
Waving his hand, Xu Chuan walked into the office, picked up the dedicated phone from his desk, and dialed the Xia Shu Aerospace Base.
After contacting Academician Chang Huaxiang, he smiled and said, "Academician Chang, it's me. There's something I need to tell you here."
On the other side of the phone, Chang Huaxiang nodded and said, "You tell me, I'll remember it."
"The Materials Research Institute made significant discoveries while collecting lunar rocks from a crater called 'Yaochi Crater'."
"Now I need to arrange manpower at the Shu Shu Space Base and the Lunar Outpost Scientific Research Station to conduct the most detailed investigation of this crater. I will send you the relevant requirements in the future."
Having said this, he then added: "Oh, by the way, the priority of the projects related to this investigation is Category S."
Hearing this, the expression on the face of Academician Chang Huaxiang on the other side of the phone changed, and he quickly replied: "Okay, I will have someone carry out relevant work as soon as I receive the information."
In the research of Xinghai Research Institute, the hierarchical planning of projects is unified and roughly divided into six categories: S, A, B, C, D, and F.
Among them, F level is the lowest and is a project derived from a D type ordinary research project. The resources that can be mobilized are limited to the project itself.
If there are additional resources, they need to be reported to Category D projects first, and then the person in charge of Category D projects can apply.
And S-class is the highest level.
For a project of this level, when there is a demand for resources, all departments of the entire institute need to complete resource integration and manpower arrangements as quickly as possible, and even suspend some original research and allocate manpower and material resources to cooperate with relevant
work.
For Xu Chuan to evaluate it as an S-level priority, Chang Huaxiang can imagine how important this discovery on the moon is.
Although he didn't know if any of the other three major research institutes had S-level projects, the Aerospace Research Institute had only two S-level projects.
Yes, the Aerospace Research Institute and the Xiashu Space Base can now be said to be the core and backbone of China's aerospace force, but they only have two S-class projects in hand.
They are the construction of the lunar outpost scientific research station base and the construction of the lunar orbital mass projector.
However, the lunar biosphere project, the manned landing project, and even the previous second-generation space shuttle research and development were not included in the S-level projects and were only evaluated as category A. You can imagine the importance of this discovery.
It is no exaggeration to say that every S-level project in Xinghai Research Institute can affect the development of the entire country and even the world.
