以碳纳米管为基础的全晶片数字电路首次研制成功

Stanford engineers perfecting carbon nanotubes for highly energy-efficient computing

最近，美国斯坦福和南加州大学工程师开发出一种设计碳纳米管线路的新方法．首次能生产出一种以碳纳米管为基础的全晶片数字电路，即使在许多纳米管发生扭曲偏向的情况下．整个线路仍能工作。碳纳米管（CNTS）超越了传统的硅技术．在能效方面有望比硅基线路提高10倍。第一个初级纳米管晶体管诞生于1998年．人们期望这将开启一个高能效．先进计算设备新时代．但受制于碳纳米管本身固有的缺点．这一愿景一直未能实现。

Carbon nanotubes represent a significant departure from traditional silicon technologies and offer a promising path to solving the challenge of energy efficiency in computer circuits, but they aren＇t without challenges. Now, engineers at Stanford have found ways around the challenges to produce the first full-wafer digital logic structures based on carbon nanotubes.
