INVESTIGATION OF CHALCOGENIDE GLASSY SEMICONDUCTORS IN THE

The study of chalcogenide glassy semiconductors (ChGS) in the Ben-Gurion University (Israel) started in early 1992 and was based on the results obtained in the A. F. Ioffe Physico-Technical Institute (St. Petersburg, Russia). Most investigations were performed in the following directions: structural transformations induced by short intense light pulses, photoinduced optical anisotropy, photoinduced electrical anisotropy, polarization-dependent anisotropic photocrystallization, Zn-photodoping, application of ChGS for development of microlens arrays and photonic band-gap structures. Main results of these investigations are reviewed shortly in this paper
