Abstract

Growth of strained semiconductors can lead to self-assembly of interesting structures such as quantum dots. Simulation of this growth requires an accurate and efficient model for the interactions of lattice mismatched materials. We present a potential for calculating the bond energies in a diamond-like crystal of silicon and germanium. With this potential we predict the strain profiles in an embedded quantum dot and discuss the mechanisms of island formation.
