Symmetry-controlled singlet-triplet transition in a double-barrier quantum ring
Heidi Potts, Josef Josefi, I-Ju Chen +6
We engineer a system of two strongly confined quantum dots to gain reproducible electrostatic control of the spin at zero magnetic field. Coupling the dots in a tight ring-shaped p…

Gate control, g-factors and spin orbit energy of p-type GaSb nanowire quantum dot devices
Sven Dorsch, In-Pyo Yeo, Sebastian Lehmann +3
Proposals for quantum information applications are frequently based on the coherent manipulation of spins confined to quantum dots. For these applications, p-type III-V material sy…
