Abstract

ZnO thin films and nanowires (NWs) were precisely treated by focused electron-beam (E-beam) irradiation with a line width between 200 nm and 3 μm. For both ZnO films and NWs, an increased green emission was clearly observed for the E-beam-treated parts. Using a high-resolution laser confocal microscope, the photoluminescence intensities for E-beam-treated ZnO structures increased with increasing dose 1.0 × 10¹⁷-1.0 × 10¹⁸ electrons/cm². The resistivity of a single ZnO NW increased from 56 to 1800 Ω cm after the E-beam treatment. From the results for the annealed ZnO thin films, we analyzed that the variations in PL and resistivity were due to the formation of vacancies upon focused E-beam irradiation.
