Electronic properties of phosphorene and graphene nanoribbons with edge vacancies in magnetic field
Jan Smotlacha, Richard Pincak
The graphene and phosphorene nanostructures have a big potential application in a large area of actuals research in physics. However, their methods of synthesis still do not allow…
Electronic Properties of Carbon Nanostructures
Jan Smotlacha, Richard Pincak
The carbon nanostructures are perspective materials for the future applications. This has two reasons: first, the hexagonal atomic structure which enables a high molecular variabil…
Electronic Properties of Bilayer Fullerene Onions
R. Pincak, V. V. Shunaev, J. Smotlacha +2
The HOMO-LUMO gaps of the bilayer fullerene onions were investigated. For this purpose, the HOMO and LUMO energies were calculated for the isolated fullerenes using the parametriza…
Green Function Approach for Calculation of the Local Density of States in the Graphitic Nanocone
Jan Smotlacha, Richard Pincak
Graphene and other nanostructures belong to the center of interest of today's physics research. The local density of states of the graphitic nanocone influenced by the spin-orbit i…
Emergence of F(R) gravity-analogue due to defects in graphene
Alireza Sepehri, Richard Pincak, Ahmed Farag Ali
We show that the defects of graphene, which lead to the non-equality between positive curvature of fermions with anti-parallel spins and negative curvature of fermions with paralle…
