Abstract

Be diffusion during post-growth annealing has been studied in InGaAs epitaxial layers. To explain the observed concentration profiles, two models have been proposed. A good agreement has been obtained between experimental and calculated data. The point defect concentration in epitaxial layers during diffusion in InGaAs is also discussed.

快速退火过程中InGaAs外延层中的Be扩散:有效扩散率方法和非平衡模型
在InGaAs外延层中研究了生长后退火过程中Be的扩散。为了解释观测到的浓度分布,提出了两个模型。实验结果与计算结果吻合较好。讨论了InGaAs扩散过程中外延层中的点缺陷浓度。
