Abstract

We have studied the characteristics of Raman scattering spectroscopy from $_ZnS{1-x}Te_x$ alloys in the whole range of Te composition x. The Raman spectra showed two-mode behaviors for those alloys. The Raman line shape showed the changes of an asymmetry and broadening of that with Te composition x. The asymmetric broadening of the line shape could be explained with a spatial correlation model.

$_ZnS{1-x}Te_x$삼원 화합물의 전 영역에서 상온 라만 스펙트럼을 연구하였다. 격자진동 모드가 두 방식의 거동을 보이고, Te 조성비 x에 따라 라만 선 모양의 비대칭성과 넓어짐이 변하였다. 선 모양의 비대칭성 넓어짐은 공간적인 상호관계(spatial correlation)모형을 이용하여 설명하였다.
