  • Abstract
    The piezoelectric photoacoustic (PPA) spectra of bulk CuInS2 single crystals grown by a traveling heater method were observed at 80 K. Two PPA signals which are due to bandgap energy and an intrinsic defect are clearly observed. The activation energy of the intrinsic defect is estimated to be about 70 meV are obtained as nonradiative recombination centers for the first time
