Paper Abstract

The photoacoustic spectroscopy with a piezoelectric transducer was employed to evaluate the band gaps of a series of Zn1- xMgxSe mixed crystals of different composition. The measurements were performed at 300 K, 90 K and 6 K. The Jackson-Amer model of photoacoustic effect for thermally thin and optically thick samples was applied. For samples of x greater than 0.18 (wurtzite structure) subgap optical absorption was observed.
