Abstract

Pulsed laser deposition technique was used to prepare the ZnMgO thin films on c-sapphire substrate at different oxygen partial pressures. Results shows that the change in oxygen partial pressure during growth changes the Mg contents in MgZnO samples, which ultimately results in samples with different structural and optical properties. Change in phase of ZnMgO thin films from cubic rock salt to hexagonal wurtzite was observed with the increase in oxygen partial pressure. A decrease in bandgap from 5.78 eV to 4.04 eV was also observed by increasing the oxygen partial pressure.
