Abstract

We have studied the electronic transport characteristics of nanowire field effect transistors (NWFETs) made from phase-pure wurtzite (WZ) and zinc blende (ZB) InAs nanowires (NWs). The electronic characteristics were obtained at temperatures between 4 and 300 K. The ZB NWFETs exhibited a greater sensitivity to the surrounding atmosphere than WZ NWFETs. The WZ NWFETs had a higher mobility than ZB NWFETs at a given temperature. We also found that WZ NWs had a higher carrier density than ZB NWs at most temperatures, presumably due to differences in carbon incorporation during growth.
