- Abstract
The role of elastic interaction has been well recognized for various growth modes and nanostructural self-organization on solid surfaces. Examples include spontaneous formation of stress domains in reconstructed surfaces or in-phase-separating monolayers, meandering and bunching of surface steps, and quantum dot formation in heteroepitaxial thin film growth. The long-range spatial ordering in these strain-mediated nanostructural evolution phenomena on solid surfaces is critically dependent on the anisotropy. A universal formulation has been developed to examine the energetically favored orientation with respect to parameters that represent the anisotropy in elasticity and applied stress.
