Cavity enhancement of V2 centers in 4H-SiC with a fiber-based Fabry-Pérot microcavity
Jannis Hessenauer, Jonathan Körber, Misagh Ghezellou +5
Silicon vacancy centers in 4H-silicon carbide (SiC) host a long-lived electronic spin and simultaneously possess spin-resolved optical transitions, making them a great candidate fo…
Discovery of ST2 centers in natural and CVD diamond
Jonas Foglszinger, Andrej Denisenko, Georgy V. Astakhov +5
The ST2 center is an optically addressable point defect in diamond that facilitates spin initialization and readout. However, while this study presents the discovery of ST2 centers…
