Controlling thermoelectric, heat, and energy currents through a quantum dot in sequential and cotunneling Coulomb-blockade regimes
Taha Yasin Ahmed, Nzar Rauf Abdullah, Vidar Gudmundsson
Thermal transport through a Coulomb-blockade quantum dot (QD) coupled to two metallic leads is studied using five different approaches to the master equation in which sequential an…
Unified approach to cyclotron and plasmon resonances in a periodic 2DEG hosting the Hofstadter butterfly
Vidar Gudmundsson, Vram Mughnetsyan, Nzar Rauf Abdullah +3
We present theoretical calculations for the cyclotron resonance and various magnetoplasmon modes of a Coulomb interacting two-dimensional GaAs electron gas (2DEG) modulated as a la…
DFT study of tunable electronic, magnetic, thermal, and optical properties of a GaSi monolayer
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Vidar Gudmundsson
The electrical, magnetic, thermal and optical characteristics of Gallium (Ga) doped silicene are investigated using density functional theory (DFT). The effect of doping is studied…
High thermoelectric and optical conductivity driven by the interaction of Boron and Nitrogen dopant atoms with a 2D monolayer Beryllium Oxide
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Vidar Gudmundsson
The electronic, thermal and optical properties of a monolayer BeO with Boron (B) and Nitrogen (N) co-dopant atoms are studied by means of a density functional theory computation. O…
Enhanced electronic and optical responses of Nitrogen- or Boron-doped BeO monolayer: First principle computation
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Hunar Omar Rashid +3
In this work, the electronic and optical properties of a Nitrogen (N) or a Boron (B) doped BeO monolayer are investigated in the framework of density functional theory. It is known…
Modulation of electronic and thermal proprieties of TaMoS by controlling the repulsive interaction between Ta dopant atoms
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Hunar Omar Rashid +2
We theoretically study the electronic and the thermal characteristics of Tantalum, Ta, doped Molybdenum disulfide, MoS, using density functional theory. It has been shown that…
