摘要
提出ρ和(Ze—Z_h)耦合试探波函数,计算了 GaAs/Ga_(I-x)Al_xAs量子阱中基态激子的结合能随阱宽和阱深的变化关系,并对所得结果进行了讨论。
Trial wave functions of p and (Ze—Zn) to Couple are devel- oped in this paper,the binding energies of ground excitons in GaAs/Ga_(1-x) Al_xAs quantum wells are calculated.The variations of binding energies with the well width and well depth are obtained and their behavior is discussed.
