Anisotropic transport in ballistic bilayer graphene cavities
Florian Schoeppl, Alina Mrenca-Kolasinska, Ming-Hao Liu +3
Closing the gap between ray tracing simulations and experimentally observed electron jetting in bilayer graphene (BLG), we study all-electronic, gate-defined BLG cavities using tig…
Finite difference method for Dirac electrons in circular quantum dots
B. Szafran, A. Mrenca-Kolasinska, D. Zebrowski
A simple and reliable finite difference approach is presented for solution of the Dirac equation eigenproblem for states confined in rotationally symmetric systems. The method sets…
Imaging spin-resolved cyclotron trajectories in the InSb two-dimensional electron gas
Alina Mrenca-Kolasinska, Krzysztof Kolasinski, Bartłomiej Szafran
We consider spin-resolved cyclotron trajectories in a magnetic focusing device with quantum point source and drain contacts defined within the InSb two-dimensional electron gas and…
Spin-active devices based on graphene / WSe heterostructure
Alina Mrenca-Kolasinska, Bartlomiej Rzeszotarski, Bartlomiej Szafran
We consider graphene on monolayer WSe and the spin-orbit coupling induced by the transition-metal dichalcogenide substrate for application to spin-active devices. We study quan…
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…
