Widebandgap semiconductors. Undoped and Mg-, Co-, Cd-, Nd-, Y-, La-doped ZnO films grown by radiofrequency and direct current magnetron sputtering and metal-organic chemical vapor deposition methods as well as investigation of their structure, microstructure, optical properties and photocatalytic activity. I am well versed in various physical methods of film analysis to study morphology, structure, electrical and optical properties.
