Electron-hole superfluidity in strained Si/Ge type II heterojunctions
Sara Conti, Samira Saberi Pouya, Andrea Perali +5
Excitons are promising candidates for generating superfluidity and Bose-Einstein Condensation (BEC) in solid state devices, but an enabling material platform with in-built bandstru…
Experimental conditions for observation of electron-hole superfluidity in GaAs heterostructures
Samira Saberi-Pouya, Sara Conti, Andrea Perali +4
The experimental parameter ranges needed to generate superfluidity in optical and drag experiments in GaAs double quantum wells are determined, using a formalism that includes self…
Anisotropic charge density wave in electron-hole double monolayers: Applied to phosphorene
S. Saberi-Pouya, M. Zarenia, T. Vazifehshenas +1
The possibility of an inhomogeneous charge density wave phase is investigated in a system of two coupled electron and hole monolayers separated by a hexagonal boron nitride insulat…
High temperature electron-hole superfluidity with strong anisotropic gaps in double phosphorene monolayers
S. Saberi-Pouya, M. Zarenia, A. Perali +2
Excitonic superfluidity in double phosphorene monolayers is investigated using the BCS mean-field equations. Highly anisotropic superfluidity is predicted where we found that the m…
Plasmon modes in monolayer and double-layer black phosphorus under applied uniaxial strain
S. Saberi-Pouya, T. Vazifehshenas, M. Saleh +2
We study the effects of an applied in-plane uniaxial strain on the plasmon dispersions of monolayer, bilayer and double-layer phosphorene structures in the long-wavelength limit wi…
Anisotropic hybrid excitation modes in monolayer and double-layer phosphorene on polar substrates
S. Saberi-Pouya, T. Vazifehshenas, T. Salavati-fard +1
We investigate the anisotropic hybrid plasmon-SO phonon dispersion relations in monolayer and double-layer phosphorene systems located on the polar substrates, such as SiO2, h-BN a…
Strong anisotropic optical conductivity in two dimensional puckered structures: The role of Rashba effect
S. Saberi-Pouya, T. Vazifehshenas, T. Salavati-fard +2
We calculate the optical conductivity of an anisotropic two-dimensional system with Rashba spin-flip excitation within the Kubo formalism. We show that the anisotropic Rashba effec…
Coulomb drag in anisotropic systems: a theoretical study on a double-layer phosphorene
S. Saberi-Pouya, T. Vazifehshenas, M. Farmanbar +1
We theoretically study the Coulomb drag resistivity in a double-layer electron system with highly anisotropic parabolic band structure using Boltzmann transport theory. As an examp…
