Realization of ZnSe-based Field-Effect Transistors operating at Cryogenic Temperatures as a Platform for Future Spin-Qubit Applications
Christine Falter, Yurii Kutovyi, Nils von den Driesch +12
The wide-bandgap compound semiconductor ZnSe is a promising host material for the realization of electron spin-qubits. Its non-degenerate conduction band and the potential for isot…
Correlations between cascaded photons from spatially localized biexcitons in ZnSe
Robert M. Pettit, Aziz Karasahin, Nils von den Driesch +3
Radiative cascades emit correlated photon pairs, providing a pathway for the generation of entangled photons. The realization of a radiative cascade with impurity atoms in semicond…
Thermally activated diffusion and lattice relaxation in (Si)GeSn materials
Nils von den Driesch, Stephan Wirths, Rene Troitsch +5
Germanium-Tin (GeSn) alloys have emerged as a promising material for future optoelectronics, energy harvesting and nanoelectronics owing to their direct bandgap and compatibility w…
Tailoring mechanically-tunable strain fields in graphene
M. Goldsche, J. Sonntag, T. Khodkov +7
There are a number of theoretical proposals based on strain engineering of graphene and other two-dimensional materials, however purely mechanical control of strain fields in these…
Electrical resistance of individual defects at a topological insulator surface
Felix Lüpke, Markus Eschbach, Tristan Heider +10
Three-dimensional topological insulators host surface states with linear dispersion, which manifest as a Dirac cone. Nanoscale transport measurements provide direct access to the t…
Suppression of contact-induced spin dephasing in graphene/MgO/Co spin-valve devices by successive oxygen treatments
F. Volmer, M. Drögeler, E. Maynicke +5
By successive oxygen treatments of graphene non-local spin-valve devices we achieve a gradual increase of the contact resistance area products () of Co/MgO spin injection and…
Role of MgO barriers for spin and charge transport in Co/MgO/graphene non-local spin-valve devices
F. Volmer, M. Drögeler, E. Maynicke +4
We investigate spin and charge transport in both single and bilayer graphene non-local spin-valve devices. Similar to previous studies on bilayer graphene, we observe an inverse de…
