A novel approach to model semiconductor quantum dots and their high temperature interdiffusion effects in 3-D was developed. It was observed that both electronic and optical properties of the dot alter significantly under moderately high temperature treatment during epitaxial growth. The model will predict the process temperature that can be tolerated by the quantum-dots during epitaxial growth and post growth processing to increase the manufacturing yield. The advantage of the model is the significant reduction of routine calculations to handle the masive and complex Hamiltonian matrix.
