Abstract

In this paper we report computer simulations which explain the self-organized growth of quantum dots in the Stranski–Krastanov growth mode of strained semiconductor systems as used, e.g., for quantum dot lasers. Because of the broad range of materials where this effect occurs we adopt an approach via a simple kinetic Monte Carlo simulation. The formation of regular arrays of equally sized quantum dots is explained by the nonlinear interplay of deposition and surface diffusion, and the strain field.

    Citation Excerpt :

    With increasing temperature, the branch width of the fractal cluster becomes wider and the cluster tends to become a compact one [1,5,6]. On the other hand, existing clusters generate an elastic strain field whch is caused by the lattice mismatch [7,8]. This strain field influences detachment from cluster boundaries and the motion of diffusing particles in the vicinity of clusters through a position-dependence energy correction term Estr.
