TT 14: Focus Session: Graphene Quantum Dots (joint session HL/TT)

Montag, 27. März 2023, 15:00–17:45, POT 251

Quantum dots have emerged as one of the contenders for a future quantum information processor. Bilayer graphene is now established as a material that allows high quality bi-polar Coulomb blockade measurement, time-dependent transport measurements and first relaxation time measurements. In contrast to the more conventional GaAs and Si-based systems, several exiting and unexpected observations in graphene have been explained by the peculiar graphene bandstructure, which is gate- tunable, the additional valley degree of freedom, and spin-valley coupling.
