摘要: Thermal annealing effect on InAs quantum dots grown vicinal (100) GaAs substrates is studied in comparison with exact substrates. We find that acts stronger by greatly accelerating the degradation of material quality. as well slightly increasing blueshift emission wavelength and narrowing PL linewidth. It attributed to higher strain formed
