Abstract:
Scientists at Motorola Labs are researching ways to improve control in the growth of carbon nanotubes (CNTs) that can make transistors smaller and faster and chemical/biological detectors ultra-sensitive. One of the technical challenges associated with CNT-based device technology is in controlling the placement of nanotubes with specific properties on a substrate. The Motorola Labs team has developed a technique using chemical vapor deposition (CVD) that can position individual single-walled carbon nanotubes at pre-determined locations on a substrate in a highly parallel manner that is compatible with conventional semiconductor processing techniques.
