Gate controlled quantum dots in monolayer WSe2
Justin Boddison-Chouinard, Alex Bogan, Norman Fong +10
Quantum confinenement and manipulation of charge carriers are critical for achieving devices practical for quantum technologies. The interplay between electron spin and valley, as…
Spin-valley qubits in gated quantum dots in a single layer of transition metal dichalcogenides
Abdulmenaf Altıntaş, Maciej Bieniek, Amintor Dusko +3
We develop a microscopic and atomistic theory of electron spin-based qubits in gated quantum dots in a single layer of transition metal dichalcogenides. The qubits are identified w…
Effects of random atomic disorder on the magnetic stability of graphene nanoribbons with zigzag edges
K. E. Çakmak, A. Altıntaş, A. D. Güçlü
We investigate the effects of randomly distributed atomic defects on the magnetic properties of graphene nanoribbons with zigzag edges using an extended mean-field Hubbard model. F…
Defect induced Anderson localization and magnetization in graphene quantum dots
A. Altıntaş, A. D. Güçlü
We theoretically investigate the effects of atomic defect related short-range disorders and electron-electron interactions on Anderson type localization and the magnetic properties…
Effects of long-range disorder and electronic interactions on the optical properties of graphene quantum dots
A. Altıntaş, K. E. Çakmak, A. D. Güçlü
We theoretically investigate the effects of long-range disorder and electron-electron interactions on the optical properties of hexagonal armchair graphene quantum dots consisting…
Magnetic Phases of Graphene Nanoribbons under Potential Fluctuations
H. U. Özdemir, A. Altıntaş, A. D. Güçlü
We investigate the effects of long-range potential fluctuations and electron-electron interactions on electronic and magnetic properties of graphene nanoribbons with zigzag edges u…
Structural and optical properties of self-catalytic GaAs:Mn nanowires grown by molecular beam epitaxy on silicon substrates
Katarzyna Gas, Janusz Sadowski, Takeshi Kasama +7
Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron m…
