| | Based on the effective mass theory, the conditon of normal-incidence absorption of intersubband transitions for n-type semiconductor quantum well(QW)infrared detector was derived by using the expression of matrix element of intersubband transition in the conduction band. Using some simple mathematical methods, the absorption coefficient of normal-incidence radiation can be represented as an analytical function of the growth direction of QWs.The optimization, the limitation of normal-incidence absorption and... | | 基于有效质量理论,从导带子带间光跃迁矩阵元的表达式出发,推出n型半导体量子阱红外探测器的正入射吸收条件.用一些简单的数学手段,把正入射的吸收系数表达力量子阱生长方向的解析函数,进而讨论正入射吸收的优化、极限及与平行吸收的比较.在考虑了椭球等能面的简并度和占有度后,在掺杂浓度为10(18)cm(-3)和探测波长10μm时,对4种具体的量子阶材料进行了计算.推荐了为获取最大正入射吸收的优化量子阱生长方向,为正入射量子阱探测器的设计提供依据. | | 文摘来源 | |   |
