SnO 2 nanowire arrays and electrical properties synthesized by fast heating a mixture of SnO 2 and CNTs waste soot

Abstract

SnO 2 nanowire arrays were synthesized by fast heating a mixture of SnO 2 and the carbon nanotubes waste soot by high-frequency induction heating. The resultant SnO 2 nanowires possess diameters from 50 to 100 nm and lengths up to tens of mircrometers. The field-effect transistors based on single SnO 2 nanowire exhibit that as-synthesized nanowires have better transistor performance in terms of transconductance and on/off ratio. This work demonstrates a simple technique to the growth of nanomaterials for application in future nanoelectronic devices. © To the authors 2009.
