Model Estimations of Fluorografene Properties

Abstract

Analytical expressions for the electronic band dispersion were derived using the Green’s function method in the tight binding approximation. A parabolic approximation of the spectrum is proposed, within which the effective carrier mass and quantum capacitance are determined. Using the Koster–Slater and Haldane—Anderson models, the problem of local states of mono- and divacancies are considered. Characteristic phonon frequencies and elastic constants are estimated. The results obtained are compared to the calculation data of other studies.
