The Nanotube Research Center of the National Institute of Advanced Industrial Science and Technology (AIST) has succeeded in the realization of an integrated 3D CNT device using single-wall carbon nanotube (CNT). With the development of the "carbon nantotube wafer (CNT wafer)," with high-density and well-aligned aggregate of CNT, it succeeded in producing a designed CNT device in large numbers. As an illustration, it has successfully accumulated more than 1,000 CNT device architectures with complicated 3D geometry on a substrate by controlling position and shape freely. Additionally, it has succeeded in electrically driving of CNT device architectures, coming much closer to practical applications of CNT devices.
