Giant valley-isospin conductance oscillations in ballistic graphene
Clevin Handschin, Péter Makk, Peter Rickhaus +6
At high magnetic fields the conductance of graphene is governed by the half-integer quantum Hall effect. By local electrostatic gating a \textit{p-n} junction perpendicular to the…
Probing Spin Helical Surface States in Topological HgTe Nanowires
Johannes Ziegler, Raphael Kozlovsky, Cosimo Gorini +10
Nanowires with helical surface states represent key prerequisites for observing and exploiting phase-coherent topological conductance phenomena, such as spin-momentum locked quantu…
Few-layer graphene patterned bottom gates for van der Waals heterostructures
Martin Drienovsky, Andreas Sandner, Christian Baumgartner +6
We introduce a method of local gating for van der Waals heterostructures, employing a few-layer graphene patterned bottom gate. Being a member of the 2D material family, few-layer…
Tuning anti-Klein to Klein tunneling in bilayer graphene
Renjun Du, Ming-Hao Liu, Jens Mohrmann +5
We show that in gapped bilayer graphene, quasiparticle tunneling and the corresponding Berry phase can be controlled such that it exhibits features of single layer graphene such as…
Fabry-Pérot resonances in a graphene/hBN Moiré superlattice
Clevin Handschin, Péter Makk, Peter Rickhaus +5
While Fabry-Pérot resonances and Moiré superlattices are intensively studied in graphene on hexagonal boron nitride (hBN), the two effects have not been discussed in their coexiste…
