Silicon on a graphene nanosheet with triangle- and dot-shape: Electronic structure, specific heat, and thermal conductivity from first-principle calculations
Hunar Omar Rashid, Nzar Rauf Abdullah, Vidar Gudmundsson
The electronic structure, specific heat, and thermal conductivity of silicon embedded in a monolayer graphene nanosheet are studied using Density Functional Theory. Two different s…
The interplay of electron-photon and cavity-environment coupling on the electron transport through a quantum dot system
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
We theoretically investigate the characteristics of the electron transport through a two-dimensionala quantum dot system in the -plane coupled to a photon cavity and a photon r…
Cavity-photon induced high order transitions between ground states of quantum dots
Vidar Gudmundsson, Nzar Rauf Abdullah, Chi-Shung Tang +2
We show that quantum electromagnetic transitions to high orders are essential to describe the time-dependent path of a nanoscale electron system in a Coulomb blockage regime when c…
Manifestation of the Purcell effect in current transport through a dot-cavity-QED system
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
We study the transport properties of a wire-dot system coupled to a cavity and a photon reservoir. Tuning the photon energy, Rabi-resonant states emerge and in turn resonant curren…
The photocurrent generated by photon replica states of an off-resonantly coupled dot-cavity system
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
Transport properties of a quantum dot coupled to a photon cavity are investigated using a quantum master equation in the steady-state regime. In the off-resonance regime, when the…
Oscillations in electron transport caused by multiple resonances in a quantum dot-QED system in the steady-state regime
Nzar Rauf Abdullah, Chi-Shung Tang, Andrei Manolescu +1
We model the electron transport current as the photon energy is swept through several resonances of a multi-level quantum dot, embedded in a short quantum wire, coupled to photon c…
