Abstract
InSb nanowires have been formed by electrodeposition in porous anodic alumina templates and employed as transistor channels. The 100 nm diameter nanowires had a zinc blende crystal structure. Single-nanowire field-effect transistors (NW-FETs) with a channel length of 500 nm exhibited on-currents of similar to 40 mu A, on/off ratios of similar to 16-20, drain conductances of similar to 71 mu S and field-effect electron mobility of similar to 1200 cm(2) V(-1) s(-1). Compared with reported NW-FETs, the on-current is large and the current saturation occurs at low source-drain voltages. These characteristics can be understood in terms of velocity saturation effects with enhanced scattering. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3587638]
