Abstract
•We use a an equilibrium approach to calculate the free energy and composition distribution of InGaN/GaN quantum dot.•The energy balance method is adopted to predict critical conditions for quantum dot formation.•We find that the formation of QD depends strongly on the size of pyramid top surface.
An equilibrium approach is used to calculate the free energy and composition distribution of InGaN/GaN quantum dot located on the InGaN/GaN pyramid. The energy balance method is adopted to predict critical conditions for quantum dot formation. We find that the formation of QD depends strongly on the size of pyramid top surface. The results can fit our experiment qualitatively.
