Abstract
The results of studies by the density functional theory (DFT) method of the density of the electronic states (DOS) of supercells of the interface of defective graphene/Ge are presented. The regularities of the change in DOS in the series graphene/Ge → graphene + vacancy/Ge (GPV) are studied. The features of the distribution of the density of electronic states at the ordered vacancy–graphene/Ge interface are discussed. The nature of the bond between graphene and germanium and the adsorption properties of the GPV–Ge system are studied based on the DFT calculations and physicochemical modeling.
