Annealing Effects on GaN/ZnO/Si Structures Prepared by RF Magnetron Sputtering

Article Preview

Abstract:

This study shows the effect of thermal annealing on GaN/ZnO/Si structures prepared by rf magnetron sputtering. Thermal annealing tended to induce a different crystalline orientation from the c-axis orientation observed with as-deposited films. The sample annealed at 900 oC under excitation at 325 nm showed two emission bands centered at approximately 380 and 550 nm.
