Revealing electron-lattice decoupling by Peltier thermometry and nanoscale thermal imaging in graphene
Saurabh Kumar Srivastav, Tobias Völkl, Gary Quaresima +7
Electrical currents in low-dimensional quantum materials can drive electrons far from equilibrium, creating stark imbalance between electron and lattice temperatures. Yet, no exist…
Direct observation of vortices in an electron fluid
Amit Aharon-Steinberg, Tobias Völkl, Arkady Kaplan +12
Vortices are the hallmarks of hydrodynamic flow. Recent studies indicate that strongly-interacting electrons in ultrapure conductors can display signatures of hydrodynamic behavior…
Absence of a giant spin Hall effect in plasma-hydrogenated graphene
Tobias Völkl, Denis Kochan, Thomas Ebnet +8
The weak spin-orbit interaction in graphene was predicted to be increased, e.g., by hydrogenation. This should result in a sizable spin Hall effect (SHE). We employ two different m…
Magnetotransport in heterostructures of transition metal dichalcogenides and graphene
Tobias Völkl, Tobias Rockinger, Martin Drienovsky +4
We use a van-der-Waals pickup technique to fabricate different heterostructures containing WSe(WS) and graphene. The heterostructures were structured by plasma etching, con…
