Dark and photoconduction in astacin crystal in a sandwich cell has been studied asa function of applied field and temperature. The results suggest that a single discretetrapping level is involved in charge carrier generation and the dominant trapping levelis different for dark and photoconduction. Space charge limited current theory hasbeen used to evaluate various transport parameters. Linear excitation light intensitydependence of photocurrent suggests that the photo generation process is one photonprocess and is trap limited. Blue shift of the photoconduction action spectrum ofastacin compared to its optical absorption spectrum with illumination throgh thepositive electrode has been attributed to the difference in the rate of recombination ofcharge carriers at the surface and in the bulk when produced by radiation of differentwavelengths.
