(American Physical Society (APS), 2017-03-01)We demonstrate theoretically that the interaction of electrons in gapped Dirac materials (gapped graphene and transition-metal dichalchogenide monolayers) with a strong off-resonant electromagnetic field (dressing field) substantially renormalizes the ... -
(Springer Science and Business Media LLC, 2019-06-11)We demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. The efect is associated with the presence of time-reversal symmetry breaking ...
-
(2019-03-01)In this work, we theoretically model the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a far-infrared (FIR) photon cavity. For the transient and the intermediate time regimes, the current ...
-
(Elsevier BV, 2017-03)The conformational preference of the cyano group of the 1-cyano-1-silacyclohexane was studied experimentally by means of gas electron diffraction (GED) and dynamic nuclear magnetic resonance (DNMR) as well as by quantum chemical (QC) calculations ...
-
(Royal Society of Chemistry (RSC), 2017)Distance measurements are performed between a pair of spin labels attached to nucleic acids using Pulsed Electron–Electron Double Resonance (PELDOR, also called DEER) spectroscopy which is a complementary tool to other structure determination methods ...
-
(Royal Society of Chemistry (RSC), 2015)Mn2+ localization in hairpin 92 of the 23S ribosomal RNA (HP92) was obtained using W-band (95 GHz) DEER (double electron-electron resonance) distance measurements between the Mn2+ ion and nitroxide spin labels on the RNA. It was found to be preferably ...
-
(Elsevier BV, 2020-09)We theoretically investigate structural stability, electronic and thermal characteristic of boron and nitrogen codoped monolayer graphene using density functional theory and Boltzmann transport equation. Three types of BN dimers, ortho, meta, and para ...
-
(Elsevier BV, 2019-03)We report on the electrical properties of the AlN/4H-SiC interface using capacitance- and conductance-voltage (CV and GV) analysis of AlN/SiC MIS capacitors. The crystalline AlN layers are made by hot wall MOCVD. CV analysis at room temperature reveals ...
-
(Beilstein Institut, 2017-11-10)We present first experiments on electron beam induced deposition of silacyclohexane (SCH) and dichlorosilacyclohexane (DCSCH) under a focused high-energy electron beam (FEBID). We compare the deposition dynamics observed when growing pillars of high ...
-
(Beilstein Institut, 2018-02-14)In the current contribution we present a comprehensive study on the heteronuclear carbonyl complex H2FeRu3(CO)13 covering its low energy electron induced fragmentation in the gas phase through dissociative electron attachment (DEA) and dissociative ...
-
(American Physical Society (APS), 2018-03-02)We study exciton polaritons in a two-dimensional Lieb lattice of micropillars. The energy spectrum of the system features two flat bands formed from S and P x , y photonic orbitals, into which we trigger bosonic condensation under high power ...
-
(American Physical Society (APS), 2017-09-06)We study theoretically the Coulomb interaction between excitons in transition metal dichalcogenide (TMD) monolayers. We calculate direct and exchange interaction for both ground and excited states of excitons. The screening of the Coulomb interaction, ...
-
(Beilstein Institut, 2019-09-17)Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...
-
(IOP Publishing, 2020-04-23)We demonstrate theoretically that the interaction of electrons in the 2D materials (gapped graphene and transition metal dichalchogenide monolayer) with a strong off-resonant electromagnetic field substantially renormalizes their band structure, including ...
-
(MDPI AG, 2018-11-28)The one-dimensional object-oriented particle-in-cell Monte Carlo collision code oopd1 is applied to explore the role of secondary electron emission and electron reflection on the properties of the capacitively-coupled oxygen discharge. At low pressure ...
-
(Royal Society of Chemistry (RSC), 2016)An isoindoline-nitroxide derivative of guanine (G, "G-spin") was shown to bind specifically and effectively to abasic sites in duplex RNAs. Distance measurements on a G-labeled duplex RNA with PELDOR (DEER) showed a strong orientation dependence. Thus, ...
-
(IOP Publishing, 2017-03-27)We apply particle-in-cell simulations with Monte Carlo collisions to study the influence of the singlet metastable states on the ion energy distribution in single and dual frequency capacitively coupled oxygen discharges. For this purpose, the ...
-
(American Chemical Society (ACS), 2018-02-12)We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the ...
-
(American Physical Society (APS), 2017-10-11)It is shown theoretically that the renormalization of the electron energy spectrum of bilayer graphene with a strong high-frequency electromagnetic field (dressing field) results in the Lifshitz transition—the abrupt change in the topology of the Fermi ...

Optimal atomic structure of amorphous silicon obtained from density functional theory calculations (IOP Publishing, 2017-06-15)Atomic structure of amorphous silicon consistent with several reported experimental measurements has been obtained from annealing simulations using electron density functional theory calculations and a systematic removal of weakly bound atoms. The ...
