Popis: | Gold is deposited on sapphire (0001) substrates by vacuum sputtering to form an ensemble of nanoparticles on the surface. Then the substrates are transferred to a magnetron sputtering chamber to be heated to 650°C and coated by a ZnO layer. The resulting layers are investigated by scanning electron microscopy, atomic force microscopy, electron diffraction, and photoluminescence. It is established that the Au sublayer ensures a higher quality of the ZnO structure and enhances photoluminescence. The differences in the morphology of ZnO structures is explained by the Au aggregation during substrate heating before ZnO deposition. |
