Research of semiconductors, diploma thesis (“Optical properties CdO”), PhD thesis (“A.C. conductivity of As2Te3 chalcogenide glasses”). He built group, devoted to plasma enhanced technology and characterization of amorphous silicon (a-Si:H), contributed to development of Constant Photocurrent Method (CPM). Studied transport properties and correlation of microstructure (AFM) and electronic properties with nm resolution.
