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…
Imaging the Thermalization of Hot Carriers After Thermionic Emission Over a Polytype Barrier
Fabian Könemann, I-Ju Chen, Sebastian Lehmann +2
The thermalization of non-equilibrium charge carriers is at the heart of thermoelectric energy conversion. In nanoscale systems, the equilibration length can be on the order of the…
Electrical control of spins and giant g-factors in ring-like coupled quantum dots
Heidi Potts, I-Ju Chen, Athanasios Tsintzis +5
Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central t…
Single-nanowire, low-bandgap hot carrier solar cells with tunable open-circuit voltage
Steven Limpert, Adam Burke, I-Ju Chen +8
Compared to traditional pn-junction photovoltaics, hot carrier solar cells offer potentially higher efficiency by extracting work from the kinetic energy of photogenerated "hot car…
