Elastic effect on the adsorbate morphology is studied using a deformable lattice model in two dimensions. Surface defects such as adatoms or steps deform the substrate and induce long-range repulsive interaction inversely proportional to the square of their separations. For a heteroepitaxial overlayer the strain induces the shape transition from a monolayer to a multilayer island for a given island slze.
