Regularity Properties of Equilibrium Configurations of Epitaxially Strained Elastic Films

  title={Regularity Properties of Equilibrium Configurations of Epitaxially Strained Elastic Films},
  author={Beatrice De Maria},
We consider a variational model introduced in the physical literature to describe the epitaxial growth of an elastic film over a rigid substrate, when a lattice mismatch between the two materials is present. We establish the regularity of volume constrained local minimizers of the total energy, proving in particular the so called zero contact-angle condition between the film and the substrate.
