摘要
The natural birefringence in two chalcopyrite semiconductors AgGaS2 and CuGaS2 have been measured in the visible at both room and liquid helium temperatures. This birefringence exhibits a sign reversal and considerable dispersion near the band gap in both samples. A phenomenological quasicubic model which was proposed to explain the dispersion of natural birefringence in wurtzite-type II-VI semiconductors is found to explain our experimental results quite satisfactorily provided exciton effect is included in fitting the data at low temperature.
