''Abstract. Heteroepitaxial growth is a process where crystals are grown one layer at a time using a molecular beam in a vacuum. When strain is present these systems can form three dimensional islands often called quantum dots. This is a nanoscale process and continuum models struggle to capture many of the phenomena that occur. Kinetic Monte Carlo (KMC) is an alternative approach which is quite promising but has had limited use in strained systems due to a variety computational bottle necks. In this talk, I will outline KMC models for strained epitaxial growth and how one can go about performing simulations in an efficient manner.''
