摘要：
Modifications in the surface morphology and photoelectric properties of InSb crystals irradiated with nanosecond pulses of ruby laser are studied. The threshold energy density corresponding to the onset of surface melting was determined to be 0.14 J/cm(2). Laser-induced changes in the spectra and photoconduction kinetics are analyzed. It is demonstrated that the irradiation of InSb crystals with ruby laser pulses within a certain range of energy densities slows down the surface recombination, increases the nonequilibrium carrier lifetime, and, as a consequence, enhances the photosensitivity of crystals.
