Nephelauxetic-Effect in DMS Zn1-xCoxSe and Effect of Pressure on Nephelauxetic-Effect
摘要
Abstract
Based on the 3D electron's radial wave function of Co2+ free ion,a Nephelauxetic-effect modifying factor to modify the radial wave function is introduced when Co2+ cations are put into the crystal field of Zn1-xCoxSe.With the modified wave functions,the optical transitions for Zn1-xCoxSe crystals are calculated.Moreover,based on the first principle of physics,the influences of high-pressure to the Nephelauxetic-effect modifying factor is considered,and the high-pressure blue shift for the Zn1-xCoxSe crystal absorption spectra are calculated and a shift rate of dE/dp=0.45meV/GPa is obtained.关键词
