Research Abstract

The growth of BeO and BeZnO thin films by pulsed laser deposition was studied. A stability diagram was constructed for the growth of crystalline BeO films. It was discovered that it is possible to grow crystalline films even at room temperature. The available alloying limits were determined for both Zn- and Be-rich BeZnO semiconductor films. X-ray dosimetry function was evaluated in Be-doped ZnO films.
