摘要
本文把固体中在较大空间范围运动的粒子作为准经典粒子来描述。将已导出的能量测不准公式和激子的经典力学模型应用到电场下GaAs/GaAlAs量子阱中 ,激子能级宽度的计算结果与测量结果基本吻合 ,能较清楚、简单地解释纵向电场和横向电场下激子光吸收线宽的很大的差异。
By using concept as quasi-classical particles, the particles which move in a large range of space in solid state are described. Applying the derived formula of energy uncertainty and exciton model of classical mechanics to GaAs/GaAlAs quantum well in electric field, the calculation results of exciton energy level width are in agreement with measured results. The great different effects of perpendicular-field and parallel-field on exciton optical absorption in the quantum well can be explained clearly and simply.
