Foreign-catalyzed assisted grown nanowires deteriorate the performance of optoelectronic devices because of incorporation of foreign impurities into the nanowires. We report on growth self-catalyzed p-type GaAs nanowires (NWs) with pure zinc blende (ZB) structure, and the fabrication of single-NW-based photodetector. The carrier mobility and concentration of GaAs field effect transistor are characterized both at room temperature and at low temperature respectively. Due to the absence of stacking faults and single crystal phase of the NWs, the photodetector exhibits room-temperature high photo-responsivity over than 105 A W-1 and great specific detectivity, which outperforms previously reported NW-based photodetectors. These results demonstrate that these self-catalyzed pure-ZB GaAs NWs to be promising candidates for optoelectronics applications. In addition, optoelectronic properties of single quantum dots embedded in single nanowires will be represented with an applied magnetic field.
