... I.A. Kurova . ... The research is mainly devoted to the problems of generation, recombination and trapping of nonequilibrium carriers in amorphous hydrogenated semiconductors (a-Si:H, a-Ge:H, a-SiGe:H) and generation and relaxation of metastable states in these materials. ... Light-induced metastable states in undoped, doped and compensated a-Si:H films were studied in a wide temperature range. ... Effect of annealing on the photoelectric properties of boron-doped a-Si:H films. ...
