PINPOINT SYNTHESIS OF TUNGSTEN OXIDE NANOWIRES USING HEAT CONTROLLING LAYER

摘要

We proposed a new pinpoint heating process that uses a heat controlling layer. We used tungsten materials for the HCL and controlled the heated area where tungsten oxide nanowires were synthesized. By controlling electric current flowing through the HCL, which had broad and narrow areas, only the narrow areas of the HCL were heated to obtain the nanowires. We used the HCL whose narrow area was 5 μm and synthesized nanowires in a 3 μm × 3 μm area. We showed that we can synthesize nanowires on many spots uniformly and simutneously using a HCL with three narrow areas.
