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.…
Interplay between Aharonov-Bohm and Altshuler-Aronov-Spivak oscillations in phase-pure GaAs/InAs core/shell nanowires of different lengths
Farah BasariÄ, Kaiwen Wang, Tudor-Gabriel Dumitru +7
In GaAs/InAs core/shell nanowires, comprising a tubular conducting shell, interference phenomena observed under an axial field and originating from closed-loop states encircling th…
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…
Aharonov-Bohm and Altshuler-Aronov-Spivak oscillations in the quasi-ballistic regime in phase-pure GaAs/InAs core/shell nanowires
Farah BasariÄ, Vladan BrajoviÄ, Gerrit Behner +10
The realization of various qubit systems based on high-quality hybrid superconducting quantum devices, is often achieved using semiconductor nanowires. For such hybrid devices, a g…
