| Özet |
| A systematic study based on self-consistent dynamical simulations is presented for the spontaneous evolution of an isolated thin solid droplet on a rigid substrate, which is driven by the surface drift diffusion induced by the anisotropic capillary forces (surface stiffness) and mismatch stresses. In this work, we studied the effect of surface free energy anisotropies [weak and strong (anomalous)] on the development kinetics of the “Stranski–Krastanow” island type morphologies. The anisotropic surface free energy and the surface stiffness were treated with well accepted trigonometric functions. Although, various tilt angles and anisotropy constants were considered during simulations, the main emphasis was given on the effect of rotational symmetries associated with the surface Helmholtz free energy topography in two-dimensional space. Our computer simulations revealed the formation of an extremely thin wetting layer … |
