local atomic order of amorphous Se1−xSx alloys, x = 0.20 , 0.30 , produced by mechanical alloying were studied by Raman scattering, X-ray diffraction, EXAFS and reverse Monte Carlo simulations of their total structure factors and EXAFS oscillations on Se K edge. The results obtained were compared to those found for other Se1−xSx, x = 0 , 0.10 alloys, and the behavior of Raman modes, average coordination
摘要 通过拉曼散射、X 射线衍射、EXAFS 和反向蒙特卡罗模拟研究了机械合金化产生的非晶 Se1−xSx 合金的局部原子序,x = 0.20 , 0.30 的总结构因子和 EXAFS 在 Se K 上的振荡边缘。将获得的结果与其他 Se1-xSx、x = 0、0.10 合金的结果进行比较,并确定拉曼模式的行为、平均配位数和原子间距离以及键角分布函数随着硫浓度的增加。
