Evidence for a New Family of 2-D Honeycomb Surface Reconstructions on Si(111)

25 Feb 2020 Demuth J. E.

A new silicene-like family of reconstructed surfaces on Si111 are discussed which appears to be a polymorph to the well know family of surface reconstructions best epitomized by the 7x7 surface. Several experimental features are discussed which lead to this new conclusion, as are several recently established limitations of density functional theory that may currently limit its ability to predict such 2-D surface structures...
