All-optical coherent population trapping with defect spin ensembles in silicon carbide
Olger V. Zwier, Danny O'Shea, Alexander R. Onur +1
Divacancy defects in silicon carbide have long-lived electronic spin states and sharp optical transitions, with properties that are similar to the nitrogen-vacancy defect in diamon…
Two-laser dynamic nuclear polarization with semiconductor electrons: feedback, suppressed fluctuations, and bistability near two-photon resonance
Alexander R. Onur, Caspar H. van der Wal
We present how optical coherent population trapping (CPT) of the spin of localized semiconductor electrons stabilizes the surrounding nuclear spin bath via the hyperfine interactio…
Analysis of optical differential transmission signals from co-propagating fields in a lambda system medium
J. P. de Jong, A. R. Onur, D. Reuter +2
We analyze theoretically and experimentally how nonlinear differential-transmission spectroscopy of a lambda-system medium can provide quantitative understanding of the optical dip…
Robust recipe for low-resistance ohmic contacts to a two-dimensional electron gas in a GaAs/AlGaAs heterostructure
M. J. Iqbal, D. Reuter, A. D. Wieck +1
The study of electron transport in low-dimensional systems is of importance, not only from a fundamental point of view, but also for future electronic and spintronic devices. In th…
