| Abstract: | We have measured the piezobirefringence spectra of several II–VI compounds with zincblende (CdTe, ZnTe, ZnSe, ZnS) and wurtzite structure (CdS, ZnO) in the region of transparency. Similar studies have also been performed with rock-salt-type lead salts (PbS, PbTe). The results have been compared with theoretical prediction based on simplified models of the interband transitions and of the corresponding excitonic effects. |
