Abstract
The preparation of a highly ordered ZnO/GaN nano-heterojunction array is introduced. Combining the merits of nanolaser and plasmonic Fabry–Perot nanolaser, we designed and fabricated an ultraviolet nanolaser with Ag-dielectric hybrid film-coated n-ZnO nanowires (NWs) array on p-GaN substrate. Ultraviolet random lasing behavior from the ZnO/GaN nano-heterojunction array has been demonstrated with both optical and electrical pumping, where the surface plasmon enhancement effect in the lasing process is discussed. The numerical simulation results show the surface plasmon at the Ag/SiO2/ZnO interface may be excited and strongly compress the wave-guided modes, which were found to optimize the lasing spectrum and increase the light intensity compared to the bare NWs array. With the electric pumping of the device, the electroluminescence parameters are characterized and the underlying mechanism is also discussed.
