Understanding and Designing Phase Change Materials: Insights from Atom Probe Tomography
Jan Köttgen, Nils von den Driesch, Alexander Pawlis +1
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…
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…

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…
Two-dimensional photonic crystal cavities in ZnSe quantum well structures
Siqi Qiao, Nils von den Driesch, Xi Chen +7
ZnSe and related materials like ZnMgSe and ZnCdSe are promising II-VI host materials for optically mediated quantum information technology such as single photon sources or spin qub…
Cavity-enhanced single photon emission from a single impurity-bound exciton
Yuxi Jiang, Robert M. Pettit, Nils von den Driesch +2
Impurity-bound excitons in ZnSe quantum wells are bright single photon emitters--a crucial element in photonics-based quantum technology. But to achieve the efficiencies required f…
Single quantum emitters with spin ground states based on Cl bound excitons in ZnSe
Aziz Karasahin, Robert M. Pettit, Nils von den Driesch +3

Engineering tunable strain fields in suspended graphene by microelectromechanical systems
Jens Sonntag, Matthias Goldsche, Tymofiy Khodkov +5
Here, we present a micro-electromechanical system (MEMS) for the investigation of the electromechanical coupling in graphene and potentially related 2D materials. Key innovations o…
Tunable coupling of two mechanical resonators by a graphene membrane
G. J. Verbiest, M. Goldsche, J. Sonntag +4
Coupled nanomechanical resonators are interesting for both fundamental studies and practical applications as they offer rich and tunable oscillation dynamics. At present, the mecha…
Tunable mechanical coupling between driven microelectromechanical resonators
G. J. Verbiest, D. Xu, M. Goldsche +5
We present a microelectromechanical system, in which a silicon beam is attached to a comb-drive actuator, that is used to tune the tension in the silicon beam, and thus its resonan…
