| 摘 要： | 用固态分子束外延技术生长了高应变In0.45Ga0.55As/GaAs量子阱材料. 研究了快速热退火对高应变InGaAs/GaAs量子阱材料光学性质的影响. 本文采用假设InGaAs/GaAs量子阱中的In-Ga原子扩散为误差函数扩散并解任意形状量子阱的薛定谔方程的方法，对不同退火温度下InGaAs/GaAs量子阱室温光致发光峰值波长拟合，得到了In原子在高应变InGaAs/GaAs量子阱中的扩散系数以及扩散激活能（0.88eV) .

| Abstract: | A highly strained In_ 0.45Ga_ 0.55As/GaAs quantum well is grown by solid source molecular beam epitaxy (MBE).The effect of rapid thermal annealing on the optical properties of the highly strained InGaAs/GaAs quantum well is studied.By fitting the room temperature photoluminescence peak wavelength of the highly strained InGaAs/GaAs quantum well,we obtain the diffusion coefficients and the activation energy of In-Ga atoms interdiffusion (0.88eV). |

| Keywords: | molecular beam epitaxy highly strained In_ 0 45Ga_ 0 55As/GaAs quantum well rapid thermal annealing room temperature photoluminescence |
