Abstract

AbstractBy analogy with graphane and fluorographene, a model of graphane-like h-AB–C compounds is proposed, in which atoms A and B occupy sites of a plane hexagonal lattice and C atoms bounded with atoms A and B are arranged by the opposite sides from the AB plane. Numerical estimations are performed for the h-A3B5–C4 compounds, where atoms A, B, and C belong to the same series of the periodic table of elements. Analytical expressions have been obtained for the electronic spectrum, the quantum capacitance, the local defect states, the force constants, and the characteristic phonon frequencies.
