(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 ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021)The aim of this work is to explore the role of electronegativity and the electron power absorption mechanism in electronegative capacitively coupled oxygen and chlorine discharges. The fundamental mechanisms underlying the electron heating and the ...
-
(2023-01)Numerical simulations done at the Nanophysics Center at Reykjavík University indicate that under constant illumination from a sufficiently energetic monochromatic light source, a space-charge limited photoemission can cause current modulation in a ...
-
(2023-06-17)The trends afoot for miniaturization of high-frequency electronic devices require integration of active and passive high-frequency circuit elements within a single system. This high level of accomplishment not only calls for a cutting-edge integration ...
-
(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, 2019-07-25)We recall theoretical studies on transient transport through interacting mesoscopic systems. It is shown that a generalized master equation (GME) written and solved in terms of many-body states provides the suitable formal framework to capture both the ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10-27)Focused electron beam induced deposition (FEBID) is a nanofabrication technique wherein electron-induced reactions are used to deposit pure metals from organometallic precursors under the area of a primary electron beam. It can be used to directly ...
