Assessment of approaches for dispersive forces employing graphone as a case study
Magdalena Birowska, Maciej Marchwiany, Claudia Draxl +1
We have studied two interchange layer systems, (i) free standing partly hydrogenated graphene (graphone), and (ii) graphone on the Nickel (111) surface, to assess various density f…
General aspects of the vapor growth of semiconductor crystals - a study based on DFT simulations of the NH3/NH2 covered GaN(0001) surface in hydrogen ambient
Pawel Kempisty, Pawel Strak, Konrad Sakowski +1
Vapor growth of semiconductors is analyzed using recently obtained dependence of the adsorption energy on the electron charge transfer between the surface adsorbed species and the…
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…
On the nature of Surface States Stark Effect at clean GaN(0001) surface
Paweł Kempisty, Stanisław Krukowski
Recently developed model allows for simulations of electric field influence on the surface states. The results of slab simulations show considerable change of the energy of quantum…
Composition dependence of elastic constants in wurtzite AlGaInN alloys
Michal Lopuszynski, Jacek A. Majewski
In this paper, we analyze the dependence of elastic constants c_ij on composition for random wurtzite quater- nary AlGayInN alloy in the whole concentration range. The study takes…
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.…
Ordering in ternary nitride semiconducting alloys
Michal Lopuszynski, Jacek A. Majewski
We present a thorough theoretical study of ordering phenomena in nitride ternary alloys GaInN, AlInN, and AlGaN. Using the Monte Carlo approach and energetics based on the Keating…
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)…
Computational study of structural and elastic properties of random AlGaInN alloys
Michal Lopuszynski, Jacek A. Majewski
In this work we present a detailed computational study of structural and elastic properties of cubic AlGaInN alloys in the framework of Keating valence force field model, for which…
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…
