title: Photoinduced anisotropy of photoconductivity in amorphous As50Se50 films.
abstract: We show that photoinduced optical anisotropy in amorphous As50Se50 films is accompanied by photoinduced anisotropy of photoconductivity while both photoinduced effects are optically reversible. We suggest that microanisotropic fragments which are the feature of amorphous chalcogenide films do affect not only the light absorption but also the transport of nonequilibrium charge carriers.
