Abstract

The temperature dependences of dark conductivity and photoconductivity, spectral response of photocurrent, and photocurrent-decay curves for nominally undoped and Dy-doped (10 -3 at. %) GaSe single crystals were measured in the intrinsic- and impurity-absorption ranges. Doping of GaSe with Dy to a moderate level gives rise to intralayer ordering, contributes to interlayer bonding, reduces the density of stacking faults, improves the structural perfection of the material, and has a strong effect on its photoelectric behavior. © 1999 MAHK "Hayka/Interperiodica".
