An influence of parallel electric field on the dispersion relation of graphene - a new route to Dirac logics
Stanisław Krukowski, Jakub Sołtys, Jolanta Borysiuk +1
Ab initio density functional theory (DFT) simulations were used to investigate an influence of electric field, parallel to single and multilayer graphene on its electron dispersion…
Role of structure of C-terminated 4H-SiC(000) surface in growth of graphene layers - transmission electron microscopy and density functional theory studies
Jolanta Borysiuk, Jakub Sołtys, Rafal Bożek +5
Principal structural defects in graphene layers, synthesized on a carbon-terminated face, i.e. the SiC(000) face of a 4H-SiC substrate, are investigated using microscopic methods.…
Stacking Sequence Dependence of Graphene Layers on SiC(000-1) - Experimental and Theoretical Investigation
Jolanta Borysiuk, Jakub Sołtys, Jacek Piechota
Different stacking sequences of graphene are investigated using a combination of experimental and theoretical methods. The high-resolution transmission electron microscopy (HRTEM)…
Density functional theory study of quasi-free-standing graphene layer on 4H-SiC(0001) surface decoupled by hydrogen atoms
Jakub Soltys, Jacek Piechota, Michal Lopuszynski +1
Epitaxial graphene, grown on SiC(0001) surface, has been widely studied both experimentally and theoretically. It was found that first epitaxial graphene layer in such structures i…
A comparative DFT study of electronic properties of 2H-, 4H- and 6H-SiC(0001) and SiC(000-1) clean surfaces: Significance of the surface Stark effect
Jakub Soltys, Jacek Piechota, Michal Lopuszynski +1
Electric field, uniform within the slab, emerging due to Fermi level pinning at its both sides is analyzed using DFT simulations of the SiC surface slabs of different thickness. It…
