- Аннотация: The melting threshold of Cd0.2Hg0.8Te has been determined by numerical modeling of the irradiation of the material with nanosecond ruby-laser radiation pulses: W-n=40-50 mJ/cm(2) with initial crystal temperature T-0 = 100 K and W-m = 30-40 mJ/cm(2) at T-0 = 300 K. Laser-induced modification of the surface of the sample under irradiation with energy density W< W-m was found; it was manifested as a quenching of the stationary photoconductivity and an increase in the reflection coefficient. For laser irradiation with W above the melting threshold, the reflection coefficient increases further in the region up to W greater than or similar to 100 mJ/cm(2) and decreases for W>110 mJ/cm(2). For above-threshold irradiation, the photoconductivity signal was found to decrease monotonically with increasing energy density in the laser pulse; this can be explained by defect formation caused by laser-induced variation of the composition in the surface region.
