The theory of electron states on the dynamically deformed adsorbed surface of a solid

TL;DR

This paper derives dispersion relations for surface electron states on a dynamically deformed adsorbed crystal surface, revealing nonmonotonous dependencies of band gap width and electron concentration on adatom concentration.

Contribution

It provides a theoretical framework for understanding electron spectra on deformed adsorbed surfaces of zinc blende crystals, including nonmonotonous behavior of key electronic properties.

Findings

Dispersion relations for surface electron states are obtained.

Band gap width varies nonmonotonously with adatom concentration.

Electron concentration dependence on adatom density is nonmonotonous.

Abstract

Dispersion relations for the spectra of surface electron states on a dynamically deformed adsorbed surface of a monocrystal with the Zinc blende structure are received. It is established that the dependences of the band gap width and of the concentration of electrons on the concentration of adatoms ${{N}_{0\text{d}}}$ upon the solid surface are of nonmonotonous character.
