Figure 4From: In situ accurate control of 2D-3D transition parameters for growth of low-density InAs/GaAs self-assembled quantum dotsMicro-PL of samples 1 to 4 at 80 K. (a) Sample 1, △ = 0.15 ML, (b) sample 2, △ = 0.075 ML, (c) sample 3, △ = 0.025 ML, (d) sample 4, △ = 0. △ is the deposition difference between the QD layer and SQD layer.Back to article page
