【摘要】 从理论和实验两个方面对GaInNAs/GaAs量子阱结构基态的光跃迁能量进行研究.在理论计算过程中,分别采用电子有效质量近似法和双能级推斥模型计算了GaInNAs合金的电子空穴分立能级的能量及其带隙能,讨论了由应变引起的带隙变化量.将理论计算结果与光致发光的实验结果进行比较,两者符合得很好.并简单分析了N的加入对GaInNAs合金带隙能产生的影响.

【Abstract】 The optical transition energy in GaInNAs/GaAs QW structures is investigated from theoretical and experimental aspects.The discrete-level energy and the band-gap energy are calculated using the effective-mass approximation and two-level repulsion model,respectively.The changes in the band-gap energy due to strains are also discussed.The theoretical and experimental transition energies of GaInNAs/GaAs quantum well structures are compared,and they agree well.The effect of N on the transition energies of GaInNAs/GaAs quantum well structures is analyzed simply.
