Abstract
Infrared reflection spectra of CuInSe2 crystals are investigated for t he polarizations E parallel to c and E perpendicular to c. Contours of the reflection spectra are calculated and phonon parameters and diele ctric constants are determined. The effective charges of the Cu, In, a nd Se ions in these materials are determined. The two-phonon absorptio n spectra in CuInSe2 are investigated and the absorption bands are ide ntified from the selection rules. (C) 1997 American Institute of Physi cs.
