Paper Abstract

The steady-state photoconductivity and photoconductivity decay have been measured from T equals 90 K to 310 K in n- CuInS2 crystals. At high light intensities the dependence of photoconductivity ((Delta) (sigma) ) on excitation strength (L) is expressed by the relation (Delta) (sigma) approximately L0.5. In this excitation strength range the decay of photoconductivity with time (t) can be described by the law (Delta) (sigma) (t) approximately (1 + Ct)-1, where the constant C is proportional to the cross-section (S) for recombination of photoexcited free electron. From the (Delta) (sigma) (t) dependence the value of the cross-section was determined. The cross-section depends on the temperature according to the relation S approximately T-1.
