Figure 5From: In situ accurate control of 2D-3D transition parameters for growth of low-density InAs/GaAs self-assembled quantum dotsMicro-PL of samples 4 to 6 at 80 K. (a) Sample 4, △ = 0; sample 5, △ = −0.05 ML; sample 6, △ = −0.075 ML. (b) Sample 4, △ = 0; sample 5, △ = −0.05 ML; sample 6, △ = −0.075 ML. △ is the deposition difference between the QD layer and SQD layer.Back to article page
