(contribution withdrawn) Separation of length scales to estimate the elastic energy of a heteroepitaxially deposited crystal — •guillaume boussinot — MPIE, Duesseldorf, Germany — PGI, Forschungszentrum Juelich, Germany

In heteroepitaxy problems, the elastic energy of the system is in general a very non-trivial function of the shape of the deposited crystal. We use the separation of length scales describing this shape to estimate the elastic energy of a cylindrical crystal and find its equilibrium dimensions for a given volume.
