Dielectric Function Analysis of Cubic CdSe Using Parametric Semiconductor Model

Y. W. Jung,T. H. Ghong,S. Y. Lee,Y. D. Kim

Abstract

ZnCdSe alloy semiconductor was widely used for the optoelectronic device. And CdSe is the end-point in this material. In this work, we measured the dielectric function spectrum of cubic CdSe with Vacuum Ultra Violet spectroscopic ellipsometry and analysed this data with parametric model. As a result, we observed some of transition energy point over 6 eV and obtained the database for dielectric function spectrum, which could be used for temperature or alloy composition dependence study on optical property of CdSe.
