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…
Strong Light-Matter Coupling in Carbon Nanotubes as a Route to Exciton Brightening
Vanik A. Shahnazaryan, Vasil A. Saroka, Ivan A. Shelykh +2
We show that strong light-matter coupling can be used to overcome a long standing problem that has prevented efficient optical emission from carbon nanotubes. The luminescence from…
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…
Optical selection rules of zigzag graphene nanoribbons
V. A. Saroka, M. V. Shuba, M. E. Portnoi
We present an analytical tight-binding theory of the optical properties of graphene nanoribbons with zigzag edges. Applying the transfer matrix technique to the nearest-neighbor ti…
