Abstract

A method of forming a coating can include: preparing a substrate surface with adherent characteristics; and/or applying at least one non-carbon-based topological insulator to the substrate surface to provide a topological insulator layer on the substrate surface. The at least one non-carbon-based topological insulator can have one or more of selected optical transmittance, selected thermal conductivity, selected electrical conductivity, or selected electrical resistivity.
