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…
Ab initio calculations of third-order elastic constants and related properties for selected semiconductors
Michal Lopuszynski, Jacek A. Majewski
We present theoretical studies for the third-order elastic constants in zinc-blende nitrides AlN, GaN, and InN. Our predictions for these compounds are based on detailed…
