According to the report of the “World News†of the United States, Dai Hongjie, professor of chemistry at Stanford University, led the research team and found that graphene nanoribbons can be used as semiconductor crystal materials. This may be integrated into high-performance computer chips in the future, increasing chip speed and performance, and reducing Heat consumption, replacing most of today's silicon made chips.
Dai Hongjie led a number of doctoral and postdoctoral graduate students to carry out this research program. He said that this is the first time that academics and industry have made graphite nanoribbons with semi-conductor properties, and he hopes to make them into semiconductor transistors in the future. The material currently used in computer equipment is silicon, and it is hoped that graphite nanoribbons will one day be used in computer chips. The study was published on the 23rd issue of the online edition of PhysicalReviewLetters.
“Carbon is everywhere, and we mainly make graphite nanoribbons very small and narrow, which makes it have semi-conductor properties. Because of the large volume of carbon, the properties are similar to those of metals, and if they are small, they can have the characteristics of semi-conductor materials. This research is The combination of chemical materials and electronic applications.†Dai Hongjie pointed out that graphite nanoribbons have advantages over silicon, with faster speeds, less heat consumption, and faster computer operations. They will be candidate materials for semiconductors in the future and electronic device materials.
According to Moore's law, the amount of crystals used doubles every two years. Researchers estimate that the silicon chips may reach the maximum amount in the next 10 years and face shortages. In addition, silicon often has overheating issues. The research team made graphite nanoribbons 50,000 times thinner than human hair and has the properties of semiconductor materials. It may be used in computer chip manufacturing in the future.
However, whether graphite nanoribbons can completely replace silicon to become a new semiconductor material in the future is still in the experimental testing stage. Dai Hongjie revealed that the research plan has been supported by Intel and sponsored some research funding, and will continue to support research in the future.
Dai Hongjie also said that graphite nanoribbons have higher speed characteristics than silicon, however, because of different carbon source sources, the characteristics of each graphite nanoribbon are also different. According to different structures, they have different characteristics, and some have more semiconductor properties. Some are more metallic in nature. However, metal nanotubes can never be used in electronic devices. How to control the extraction and performance is a problem in the future use of graphite nanoribbons for semiconductor crystals.
The carbon nanotube tubes previously researched by Dai Hongjie are the same as those of the graphite nanoribbons. They are both carbon and one of the most active materials in the world. There are many laboratories in the world that are conducting carbon nanotube research.
He pointed out that carbon nanotubes can be used in very small transducers and electromechanical devices, including transistors that convert from material transport to electronic signals. He emphasized that the study of carbon nanotubes by chemical synthesis methods is not only for synthesis but also for the study of physical properties and related application prospects. The scope is quite extensive.
