Calculation results of WL growth dynamics for different InAs deposition rates at (a) 490°C and (b) 520°C. The horizontal and vertical dotted lines correspond to the critical thickness and t = 20 s, respectively. The insets of (a) and (b) zoom in the 3D growth stages. Here, we use b = 8.3 × 10−9, α = 0.85, β = 10, and Edif = 1.04 eV to solve the rate equations numerically.
