摘要：
In this study the crystal structure of MgxZn1-xO (0.0 <= x <= 0.97) layers grown on MgO/c-sapphire templates have been studied by HRXRD and HRTEM. It will be shown that the Mg composition can be controlled by Mg/Zn flux ratios. Assuming a model based on Vegard's law it is shown that ZnO alloyed in rock-salt structure MgO has a rock-salt structure whereas MgO alloyed in wurtzite structure ZnO has a wurtzite structure. HRTEM results indicate the initial stage of the MgZnO growth on MgO starts with a cubic structure even in case of wurtzite structure at the end.
