✦ Synopsis
A new method of investigating band gaps in birefringent materials by means of polarization modulation in reflection is described. Measurements at the Eo-gap of the I-III-VI2 compounds CuA1S:, CuGaS2, CulnS2 give results Similar to those found by other methods, z,5 The energy of the lowest exciton of CuA1Se2 is 2.715 eV at T = 78K.
