由于SigeSn合金材料其具有高的载流子迁移率和较长的载流子寿命,并且其结构具有较高的热力学稳定性,所以在光电子领域中是一种具有非常大应用潜力的半导体材料.本文采用密度泛函理论中的广义梯度近似ggA+U的方法,构建并计算了本征半导体Si_(96)与五组掺杂模型Si_(92)ge_(2)Sn_(2)、Si_(88)ge_(4)Sn_(4)、Si_(84)ge_(6)Sn_(6)、Si_(80)ge_(8)Sn_(8)、Si_(76)ge_(10)Sn_(10)的电子结构及光学性质.通过对计算结果的分析可知,ge,Sn的加入使得Si材料的带隙宽度减小,并且发生了由间接带隙向直接带隙的转变;ge,Sn浓度最高的SigeSn合金的形成能相对较高,稳定性相较于ge,Sn含量低的材料较差;随着ge,Sn掺杂浓度的提高,电子态密度图显示出越来越明显的杂化现象,并且态密度的峰值主要有Si原子的s轨道提供;ge,Sn浓度的提高还使得SigeSn合金的吸收系数在可见光及近红外区域内增加、反射率在可见光及以上波段范围内提高、折射率变低、消光系数曲线向红外区域移动等光学性质变化,表明可以通过调节ge,Sn浓度来获得合适的光学特性,这为SigeSn半导体在红外区域光电材料和器件的应用上提供了研究方向.
