Transverse Magnetic Surface Plasmons in Graphene Nanoribbon Qubits: The Influence of a VO2 Substrate

Author(s): Bahrami M; Vasilopoulos P;

We study the influence of the phase-change material VO2 on transverse magnetic (TM) surface plasmon (SP) modes in metallic arm-chair graphene nanoribbon (AGNR) qubits in the Lindhard approximation. We assess the effects of temperature as a dynamic knob for the transition from the insulating to the metallic phase on the TM SP modes in single-band (SB) and ...

RPA Plasmons in Graphene Nanoribbons: Influence of a VO2 Substrate

Author(s): Bahrami M; Vasilopoulos P;

We study the effect of the phase-change material VO2 on plasmons in metallic arm-chair graphene nanoribbons (AGNRs) within the random-phase approximation (RPA) for intra- and inter-band transitions. We assess the influence of temperature as a knob for the transition from the insulating to the metallic phase of VO2 on localized and propagating plasmon mode ...

Inhomogeneous linear responses and transport in armchair graphene nanoribbons in the presence of elastic scattering

Author(s): Bahrami M; Vasilopoulos P;

Within linear-response theory we derive a response function that thoroughly accounts for the in?uence of elastic scattering and is valid beyond the long-wavelength limit. We use the theory to evaluate the polarization function and the conductivity in metallic armchair graphene nanoribbons (AGNRs) in the Lindhard approximation for intra-band and inter-band ...

Defective GaAs nanoribbon-based biosensor for lung cancer biomarkers: a DFT study

Author(s): Tarun T; Singh P; Kaur H; Walia GK; Randhawa DKK; Choudhary BC;

Density functional theory-based first-principles investigation is performed on pristine and mono vacancy induced GaAs nanoribbons to detect the presence of three volatile organic compounds (VOCs), aniline, isoprene and o-toluidine, which will aid in sensing lung cancer. The study has shown that pristine nanoribbon senses all three analytes. For the pristi ...
