Multiband theory for hexagonal germanium
Yetkin Pulcu, János Koltai, Andor Kormányos +1
The direct bandgap found in hexagonal germanium and some of its alloys with silicon allows for an optically active material within the group-IV semiconductor family with various po…
Quantum interference tuning of spin-orbit coupling in twisted van der Waals trilayers
Csaba G. Péterfalvi, Alessandro David, Péter Rakyta +2
We show that in van der Waals stacks of twisted hexagonal layers the proximity induced Rashba spin-orbit coupling can be affected by quantum interference. We calculate the quantum…
Tunable Berry curvature, valley and spin Hall effect in Bilayer MoS
Andor Kormányos, Viktor Zólyomi, Vladimir I. Fal'ko +1
The chirality of electronic Bloch bands is responsible for many intriguing properties of layered two-dimensional materials. We show that in bilayers of transition metal dichalcogen…
Current-phase relation of ballistic graphene Josephson junctions
Gaurav Nanda, Juan Luis Aguilera-Servin, Péter Rakyta +7
The current-phase relation (CPR) of a Josephson junction (JJ) determines how the supercurrent evolves with the superconducting phase difference across the junction. Knowledge of th…
Magnetic field oscillations of the critical current in long ballistic graphene Josephson junctions
Péter Rakyta, Andor Kormányos, József Cserti
We study the Josephson current in long ballistic superconductor-monolayer graphene-superconductor junctions. As a first step, we have developed an efficient computational approach…
Boundary conditions for transition-metal dichalcogenide monolayers in the continuum model
Csaba G. Péterfalvi, Andor Kormányos, Guido Burkard
We derive the boundary conditions for MoS and similar transition-metal dichalcogenide honeycomb (2H polytype) monolayers with the same type of H…
