| Özet |
| A systematic study based on the self-consistent dynamical simulations is presented for the spontaneous evolution of an isolated thin solid droplet (bump) on a rigid substrate, which is driven by the surface drift diffusion induced by the capillary and mismatch stresses. In this study, we mainly focused on the development kinetics of the “Stranski–Krastanow” island type morphology, initiated by the nucleation route rather than the surface roughening scheme. The physicomathematical model, which bases on the irreversible thermodynamics treatment of surfaces and interfaces with singularities [TO Ogurtani, J. Chem. Phys. 124, 144706 (2006)], furnishes us to have autocontrol on the otherwise free-motion of the triple junction contour line between the substrate and the droplet without presuming any equilibrium dihedral contract (wetting) angles at the edges. During the development of the bell-shaped Stranski–Krastanow … |
