Description
| - Surface unit cells with a larger area and a reduced symmetry have a larger configurational entropy. The entropy may even stabilize reconstructions with higher energy at finite temperatures. We study the entropy contribution to surface reconstructions on the basis of ground-state calculations employing density-functional theory. Specifically, the ground-state GaSb(111)A surface reconstruction has a (22) symmetry, but at elevated temperatures, we experimentally observe the (2323)-R30° symmetry in agreement with the theoretical results. The findings based on the general expressions are consistent with experimental data from other semiconductor surfaces.
