A mixed II-VI semiconductor Zn[1-x]Be[x]Se possesses non-trivial vibration properties, because its two constituent compounds, ZnSe and BeSe, show very different degree of covalency and hence high elastic contrast. An anomalous Be-Se vibration line ha

We report the results of a self-consistent pseudopotential study including structural, optical, and thermodynamic properties of cubic Zn1−xBexSe semiconductor alloy. The system is modeled in various possible configurations using a large 64-atom sup
