The "5-nanometer carbon nanotube CMOS device" declared by Peking University was selected.
Chip is the foundation and driving force of the information age, and the existing CMOS technology will touch its limit.Carbon nanotube technology is considered as an important option in post-Moore era.
Theoretical studies show that CNT transistors are expected to provide higher performance and lower power consumption, and easier to achieve three-dimensional integration, system-level synthesis advantages will be up to thousands of times, the chip technology may thus be raised to new heights.
Peking University Department of Electronics Professor Peng Lianchao team made significant breakthroughs in the carbon nanotube CMOS device physics and preparation techniques, explore the performance limits and so on, to give up the traditional doping process, by controlling the electrode material to control the polarity of the transistor, inhibit short ditch For the first time, a 5 nanometer gate length high performance carbon nanotube transistor is achieved. Its performance surpasses that of the best silicon-based transistor at present, approaching the physical limit determined by the quantum mechanics principle and is expected to advance the CMOS technology to the technology node below 3 nanometers.
Marked achievements on Scaling carbon nanotube complementary transistors to 5-nm gate lengths, January 20, 2017, published online in Science, 2017, 355: 271-276; included by IBM researchers Was cited 24 times publicly in the journal Science and Nature and Nanotechnology and was selected as ESI Highly Cited Papers by the major international and domestic academic media such as Nature Index, IEEE Spectrum, Nano Today, Science and Technology Daily, And Xinhua News Agency reported;
"People's Daily" (Overseas Version) Carbon nanotube transistors 'work at three times the speed of Intel's state-of-the-art 14nm commercial silicon material transistors, consuming only a quarter of their energy, meaning that Chinese scientists' Technology catch up with foreign counterparts', 'is a new milestone in the development of China's information technology'.
