Grahic Jump Location
Broken symmetry and lattice mismatch. The substrate has square symmetry. The epilayer has rectangular symmetry, with two variants.

Schematic illustration of elastic refining; (a) a single-variant epilayer, (b) a two-variant epilayer with appropriate forces applied around the new domain, (c) the external forces removed
Grahic Jump Location
A domain pattern in the epilayer constrained on the substrate
Grahic Jump Location
The Landau expansion as a function of the order parameters. The four wells correspond to spontaneous states.
Grahic Jump Location
Domain wall shape. The domain width is on the order of b.
Grahic Jump Location
Free energy versus domain spacing. Without substrate constraint, the energy decreases as the domain size increases. With substrate constraint, the energy reaches a minimum at a specific domain size.
Grahic Jump Location
Comparison of domain evolution in simulations with substrate constraint and without. The left column is the result with substrate, and parallel domains can be seen. The right column is the result without constraint, and the structure keeps coarsening.
