Interband transitions in narrow-gap carbon nanotubes and graphene nanoribbons
R. R. Hartmann, V. A. Saroka, M. E. Portnoi
We use the robust nearest-neighbour tight-binding approximation to study on the same footing interband dipole transitions in narrow-bandgap carbon nanotubes and graphene nanoribbon…
Phosphorene quantum dot electronic properties and gas sensing
Hazem Abdelsalam, Vasil A. Saroka, Waleed O. Younis
Density functional theory calculations are performed on phosphorene quantum dots having different shapes and edge terminations to investigate their structure stability, electronic…
Hidden correlation between absorption peaks in achiral carbon nanotubes and nanoribbons
V. A. Saroka, A. L. Pushkarchuk, S. A. Kuten +1
In this paper we study the effect of absorption peak correlation in finite length carbon nanotubes and graphene nanoribbons. It is shown, in the orthogonal π-orbital tight-binding…
Tuning terahertz transitions in a double-gated quantum ring
T. P. Collier, V. A. Saroka, M. E. Portnoi
We theoretically investigate the optical functionality of a semiconducting quantum ring manipulated by two electrostatic lateral gates used to induce a double quantum well along th…
Electro-optical properties of phosphorene quantum dots
V. A. Saroka, I. Lukyanchuk, M. E. Portnoi +1
We study electronic and optical properties of single layer phosphorene quantum dots with various shapes, sizes, and edge types (including disordered edges) subjected to an external…
