✦ Synopsis

Photoconductivity spectra of n-type CuInSe, single crystals are measured in the photon energy range hv = 0.75 -3.1 eV and as a function of temperature in the range T = 80-320 K. It is found that the photoconductivity of as-grown crystals is a nearly pure surface effect, while sensitization of the crystal volume is observed only after sufficiently long annealing in the presence of powdered material. To explain the temperature dependence of the photoconductivity carrier trapping processes must be taken into account.

## Abstract Both p‐type and n‐type CuInSe~2~ single crystals were implanted with 40 keV ^130^Xe^+^ ions up to doses of 5 Β· 10^16^ cm^βˆ’2^. Implanted layers on p‐type substrates showed an initial increase of the resistivity followed by a continuous decrease of the resistivity at higher doses. Implant
