Lorentz force effects for graphene Aharonov-Bohm interferometers
Alina Mrenca-Kolasinska, Bartlomiej Szafran
We investigate magnetic deflection of currents that flow across the Aharonov-Bohm interferom- eters defined in graphene. We consider devices induced by closed n-p junctions in nano…
Imaging snake orbits at graphene n-p junctions
K. Kolasiński, A. Mreńca-Kolasińska, B. Szafran
We consider conductance mapping of the snake-orbits confined along the n-p junction defined in graphene by the electrostatic doping in the quantum Hall regime. We explain the perio…
Inter-Edge Backscattering in Buried Split-Gate-Defined Graphene Quantum Point Contacts
Shaohua Xiang, Alina Mrenca-Kolasinska, Vaidotas Miseikis +7
Quantum Hall effects offer a formidable playground for the investigation of quantum transport phenomena. Edge modes can be detected, branched, and mixed by designing a suitable pot…
Theory of ballistic quantum transport in presence of localized defects
K. Kolasiński, A. Mreńca-Kolasińska, B. Szafran
We present an efficient numerical approach for treating ballistic quantum transport across devices described by tight binding (TB) Hamiltonians designated to systems with localized…
Imaging the localization of the quasi-bound states in graphene antidots
Alina Mreńca, Krzysztof Kolasiński, Bartłomiej Szafran
We consider charge transport across a finite graphene flake with a circular antidot defined in its center. The flake is connected to thin metallic armchair nanoribbons and the stud…
