Rashba-Cavity Engineering of Energy Gaps and Spin-Hall Conductivity in Semiconducting Artificial Graphene
Maryam Mansouri, Vram Mughnetsyan, Armen Harutyunyan +2
We investigate the combined effect of a far - infrared cavity field and Rashba spin - orbit interaction on the band structure and transport properties of artificial graphene compos…
Effect of two-dimensional nonlocal screening on mobility of electrons in transition-metal dichalcogenide monolayers
Aram Manaselyan, Vram Mughnetsyan, Anna Asatryan +1
A new mechanism for charge carrier scattering in transition-metal dichalcogenide monolayers is proposed on the basis of the theory of two-dimensional nonlocal screening developed f…
Enhanced Efficiency of Intermediate-Band Semiconductor Solar Cells Embedded with Quantum Dot Superlattices
Naira Petrosyan, Lilit Yeganyan, Aram Manaselyan +3
We present a multiscale approach for modeling an intermediate-band solar cell based on a GaAs-GaAlAs quantum dot superlattice of cubic symmetry. Our framework combines high-accurac…
Magneto-optical properties of electron gas in a chain of planar quantum rings: Effect of screening on the signature of quantum phase interference
Armen Harutyunyan, Vram Mughnetsyan, Albert Kirakosyan +1
The equilibrium properties and interminiband transitions for Hartree-interacting two-dimensional electron gas in a one-dimensional chain of planar quantum rings subjected to a tran…
