Pauli blockade microscopy of quantum dots
E. Wach, B. Szafran
We propose a spin-sensitive scanning probe microscopy experiment on double quantum dots in Pauli blockade conditions. Electric spin resonance is induced by an AC voltage applied to…
Manipulating quantum Hall edge channels in graphene through Scanning Gate Microscopy
Lennart Bours, Stefano Guiducci, Alina Mreńca-Kolasińska +3
We show evidence of the backscattering of quantum Hall edge channels in a narrow graphene Hall bar, induced by the gating effect of the conducting tip of a Scanning Gate Microscope…
Spin inversion in fluorinated graphene n-p junction
Bartlomiej Rzeszotarski, Alina Mrenca-Kolasinska, Bartlomiej Szafran
We consider a dilute fluorinated graphene nanoribbon as a spin-active element. The fluorine adatoms introduce a local spin-orbit Rashba interaction that induces spin-precession for…
Imaging backscattering in graphene quantum point contacts
Alina Mreńca-Kolasińska, Bartłomiej Szafran
We study graphene quantum point contacts (QPC) and imaging of the backscattering of the Fermi level wave function by potential introduced by a scanning probe. We consider both etch…
Double quantum dots defined in bilayer graphene
D. P. Żebrowski, F. M. Peeters, B. Szafran
Artificial molecular states of double quantum dots defined in bilayer graphene are studied with the atomistic tight-binding and its low-energy continuum approximation. We indicate…
Spin-valley resolved photon-assisted tunneling in carbon nanotube double quantum dots
E. N. Osika, B. Szafran
We consider the photon-assisted tunneling (PAT) and the Landau-Zener-Stueckelberg (LZS) interference for double quantum dots induced electrostatically along a semiconducting carbon…
