IBM发明了一种制造更快速和更小的晶体管的新方法。IBM的研究人员已将1万个碳纳米管晶体管集成在硅片上。在硅晶体管正接近小型化的根本极限的时候,IBM的工作指向了一种可能的生产更小更快,也更有效的计算机的新方法。IBM较早的工作显示纳米管晶体管芯片比硅晶体管芯片快三倍,耗电量却只有后者的三分之一。而且,纳米管很小,直径只有2纳米,结构像卷起来的六角形网格。这就使芯片制造者理论上可以在一块芯片上放置远比硅晶体管更多的碳纳米管。但是将大量
IBM invented a new method of making faster and smaller transistors. IBM researchers have 10,000 carbon nanotube transistors integrated in the silicon. As silicon transistors are approaching the fundamental limits of miniaturization, IBM’s work points to a possible new way to produce smaller, faster and more efficient computers. Earlier work by IBM showed that nanotube transistor chips are three times faster than silicon transistor chips, consuming only about a third of the latter. Moreover, nanotubes are small, only 2 nanometers in diameter, structured like a rolled up hexagonal grid. This allows chipmakers to theoretically place more carbon nanotubes on a single chip than silicon transistors. But it will be plenty
