AbstractThe thermal stability of BeZnO was examined in this study. Structural relaxation and reconstruction of the BeZnO alloy film started at 500 °C and came to a halt at 800°C. Be atoms were found to be diffused out from the host position, and BeO-based second phase was formed. The bandgap of BeZnO was reduced to the value of pure ZnO after annealing at 600°C. Therefore, the thermodynamic solubility of BeO in ZnO is far below than that of MgO in ZnO. Finally, the long term stability of BeZnO at room temperature was verified after aged for one year. © 2013 AIP Publishing LLC.
