Abstract
Vertically aligned ZnO nanowires have been prepared, and structural characterization shows that the nanowires have relatively high crystalline quality. The dominant free exciton emission and the appearance of B-type exciton emissions at low temperatures reveal the high optical quality of the nanowires. Au–MgO–ZnO nanowire structures have been constructed, and random lasing has been observed from the structure under the injection of continuous current.Keywords
