Modification of the magnetic and electronic properties of the graphene-Ni(111) interface via halogens intercalation
Yong Zhou, Roman Ovcharenko, Beate Paulus +2
Electronic decoupling of graphene from metallic and semiconducting substrates via intercalation of different species is one of the widely used approaches in studies of graphene. In…
On the Role of Non-Diagonal System-Environment Interactions in Bridge-Mediated Electron Transfer
Nirmalendu Acharyya, Roman Ovcharenko, Benjamin P. Fingerhut
Bridge-mediated electron transfer (ET) between a donor and an acceptor is prototypical for the description of numerous most important ET scenarios. While multi-step ET and the inte…
Adsorption of NO2 on WSe2: DFT and photoelectron spectroscopy studies
Roman Ovcharenko, Yuriy Dedkov, Elena Voloshina
The electronic structure modifications of WSe2 upon NO2-adsorption at room and low temperatures were studied by means of photoelectron spectroscopy. We found only moderate changes…
Understanding the origin of band gap formation in graphene on metals: graphene on Cu/Ir(111)
H. Vita, S. Boettcher, K. Horn +5
Understanding the nature of the interaction at the graphene/metal interfaces is the basis for graphene-based electron- and spin-transport devices. Here we investigate the hybridiza…
Theoretical description of X-ray absorption spectroscopy of the graphene-metal interfaces
E. N. Voloshina, R. E. Ovcharenko, A. S. Shulakov +1
The present manuscript considers the application of the method of the near-edge X-ray absorption spectroscopy (NEXAFS) for the investigation of the graphene-based systems (from fre…
Specific many-electron effects in X-ray spectra of simple metals and graphene
R. E. Ovcharenko, I. I. Tupitsyn, E. P. Savinov +4
In this work the influence of many-electron effects on the shape of characteristic X-ray emission bands of the simple metals Mg and Al are examined by means of ab initio calculatio…
