The 2D outlook of graphene and similar layers has initiated a number of theoretical considerations of electronic structure that are both interesting and exciting, but applying these ideas to real layered systems, in terms of a model 2D system, must b

From the combined experimental and theoretical investigations, we suggest the formation of a honeycomb structure of BeO monolayer on the Mo(112) surface. This structure is matched to the substrate Mo(112), thus giving the (1 × 1) LEED pattern, and i

The relativistic band structures of the IV group honeycomb monolayers, from graphene to plumbene (C-Si-Ge-Sn-Pb), have been calculated within DFT in Local Density Approximation (LDA). Basing on the obtained results, we suggest that the spin-orbit cou

Electronic structures of bulk, bilayer and monolayer FeS2 are studied by DFT-GGA method. The band gap of the FeS2 monolayer is found to be of 0.73 eV, which is well below the estimated bulk value (0.85 eV). As a result, the gap reaches its maximum (1

It is found that the magnetoresistance of the Mo(110) plate non-monotonically depends on hydrogen coverage and degree of the ordering of adsorbed hydrogen layers. In particular, there is a pronounced minimum on the dependence corresponding to formati

The apparent splitting of surface bands of Cu(111), Ag(111), and Au(111) films, obtained in calculations without account for spin-orbit coupling, is usually explained as a result of interaction of surface states located at opposite surfaces of the sl

Density-functional theory (DFT) calculations show that the Na adsorption on the MoS2 (0001) surface, as well as Na intercalation into the space between MoS2 layers, transforms the semiconductor band structure of MoS2 into that of a metallic system. I

The driving force for the W(001) surface reconstruction and electronic structures of pristine and H-covered W(001) surfaces are studied by means of relativistic DFT calculations. The spin-orbit coupling leads to the splitting of the bands. Adsorbed p

The electronic structures of SnO, Sn 2 O 3 and SnO 2 layers adsorbed on the Rh(111) surface have been calculated by DFT. A drastic difference between densities of states of SnO and SnO 2 in the energy range that corresponds to O 2s and Sn 4d states c

The structures of Ag adsorbed layers on the Mo(1 1 2) surface have been studied by low energy electron diffraction (LEED) and compared with Pd structures on this surface. Performed DFT calculations have shown that the dominant interaction at low cove
