Abstract
High quality CuInS2 single crystals, grown by the traveling heater method in an indium solvent, were studied using reflectance and photoluminescence at 4.2 K. The first, EAn=2=1.5494 eV, and second, EAn=3=1.5532 eV, excited states of the A free exciton have been observed in the photoluminescence spectra. Accurate values of the A exciton binding energy EFE A =18.5 meV and Bohr radius aB A=3.8 nm, bandgap Eg=1.5540 eV at 4.2 K and static dielectric constant =10.2 have been derived assuming a hydrogenic model.
