Webinars
The DST CDT have hosted a series of Webinars on different aspects of Diamond Science and Technology. We will be adding more webinars later in the year but if you are interested and would like us to contact you with new dates please register your interest here.
Versatile diamond sensor devices
Elke Neu-Ruffing, University of Kaiserslautern
Individual color centers in diamond are stable, atomically sized quantum systems. Nitrogen vacancy (NV) centers represent coherent, isolated electronic spins [1]. Moreover, NV centers are fully optical quantum sensors via near field processes such as F枚rster resonance energy transfer (FRET). To enable nanoscale sensing, we incorporate NVs into highly functional photonic nanostructures. These tip-like structures enable scanning NV centers close (< 50 nm) to a sample to record nanoscale resolution images e.g. of magnetic fields. Simultaneously, with these structures we retrieve bright fluorescence from our NV centers rendering our sensors more sensitive. We discuss our recent achievements in optimizing nanofabrication of our sensor devices which are crucial in the context of scalability as well as commercialization [2,3]. As a very recent demonstration of all optical imaging using NV centers, we present the first realization of FRET between NV centers and a luminescent two-dimensional material, namely WSe2 [4].
