Understanding and Designing Phase Change Materials: Insights from Atom Probe Tomography
Jan Köttgen, Jan Köttgen, Nils von den Driesch +2
Phase Change Materials (PCMs) can be rapidly and reversibly switched between their amorphous and crystalline state; a transition which is accompanied by a pronounced change of opto…
Optically Active Single Hole Spin in ZnSe
Amirehsan Alizadehherfati, Yuxi Jiang, Kelsey J. Mirrielees +7
Semiconductor hole spins offer a pathway to extended coherence times by decoupling from nuclear magnetic noise, while their spin-orbit coupling enables fast all-electrical control.…
Electrical Control of Optically Active Single Spin Qubits in ZnSe
Amirehsan Alizadehherfati, Yuxi Jiang, Nils von den Driesch +6
Electrons bound to shallow donors in ZnSe quantum wells are promising candidates for optically addressable spin qubits and single-photon sources. However, their optical coherence a…
Generation of Coherent Quantum Light from a Single Impurity-Bound Exciton
Yuxi Jiang, Christine Falter, Robert M. Pettit +5
Impurity-bound excitons in II-VI direct-bandgap semiconductors are promising optically active solid-state spin qubits that combine exceptional optical quantum efficiency with an ul…
