Spin and valley manipulation in single and double electrostatic silicene quantum dots
B. Szafran, D. Zebrowski
We study single and double quantum dots defined electrostatically within silicene. The spin-valley structure of the confined single- and two-electron system is determined and the e…
Electrostatic quantum dots in silicene
B. Szafran, D. Zebrowski, A. Mrenca-Kolasinska
We study electrostatic quantum dot confinement for charge carriers in silicene. The confinement is formed by vertical electric field surrounding the quantum dot area. The resulting…
Electrical control of a confined electron spin in a silicene quantum dot
Bartlomiej Szafran, Alina Mrenca-Kolasinska, Bartlomiej Rzeszotarski +1
We study spin control for an electron confined in a flake of silicene. We find that the lowest-energy conduction-band levels are split by the diagonal intrinsic spin-orbit coupling…
Aharonov-Bohm conductance oscillations and current equilibration in local n - p junctions in graphene
Dariusz Żebrowski, Alina Mrenca-Kolasinska, Bartłomiej Szafran
We consider a small p-type island defined within n-type graphene nanoribbon induced by potential of a floating electrode. In the quantum Hall conditions the island supports persist…
Valley qubit in gated MoS monolayer quantum dot
J. Pawłowski, D. Żebrowski, S. Bednarek
The aim of presented research is to design a nanodevice, based on a MoS monolayer, performing operations on a well-defined valley qubit. We show how to confine an electron in a…
