Exciton spectroscopic control of disordered semiconductor systems properties

摘要

The II-VI semiconductor solid solutions formed by binary compounds which have different crystal structures (wurtzite -W, zinc-blende - ZB and crystals with stacking faults - SF) have been investigated. Study of exciton reflection and luminescence spectra and birefringence measurements along with X-ray analysis and microprobe control have revealed for Zn/sub x/Cd/sub 1-x/Se and Zn/sub 1-x/Mg/sub x/S solid solutions the concentration range of the ZB-W structural phase transition. The dependence of band parameters on composition has been studied in a wide range of component concentrations covering both ZB and W pure structures, as well as the ZB-W transition region.
