First Carbon Nanotube Computer Integrated With CMOS | EE Times via @eetimes

Nanometer diameter tubes of pure carbon -- nanotubes -- were heralded as the ideal transistor material a decade ago, because carbon nanotube transistors are higher-speed and lower-power than silicon transistors. Individual carbon nanotube transistors were demonstrated by IBM and others, but two problems plagued full-scale development efforts: the inability to grow them in perfectly straight arrays, and the difficulty of sorting out semiconducting- from metallic-nanotubes. As a result, most researchers today have switched from nanotubes to investigating planar carbon -- graphene -- which can be fabricated using more traditional CMOS techniques. Now Stanford researchers, led by professors Subhasish Mitra and H.S. Philip Wong, along with doctoral candidate Max Shulaker, hope to revitalize carbon-nanotube development efforts by surmounting its problems with a CMOS compatible p...
