Report

Light extraction from CVD-grown <400> single crystal diamond nanopillars. Selective charge state manipulations with 0V SF6 plasma

Autor: Radtke, Mariusz, Slablab, Abdallah, Van Vlierberghe, Sandra, Lin, Chao-Nan, Lu, Ying-Jie, Shan, Chong-Xin

We investigate the possibilities to realize light extraction from single crystal diamond (SCD) nanopillars. This was achieved by dedicated 519 nm laser-induced spin-state initiation of negatively charged nitrogen vacancies (NV-). For the first time,

Report

Plasma treatments and photonic nanostructures for shallow nitrogen vacancy centers in diamond

Autor: Radtke, Mariusz, Render, Lara, Nelz, Richard, Neu, Elke

We investigate the influence of plasma treatments, especially a 0V-bias, potentially low damage O$_2$ plasma as well as a biased Ar/SF$_6$/O$_2$ plasma on shallow, negative nitrogen vacancy (NV$^-$) centers. We ignite and sustain using our 0V-bias pl

Reliable Nanofabrication of Single-Crystal Diamond Photonic Nanostructures for Nanoscale Sensing

Autor: Radtke, Mariusz, Nelz, Richard, Slablab, Abdallah, Neu, Elke

Publikováno v: Micromachines 2019, 10(11), 718

In this manuscript, we outline a reliable procedure to manufacture photonic nanostructures from single-crystal diamond (SCD). Photonic nanostructures, in our case SCD nanopillars on thin (< 1$\mu$m) platforms, are highly relevant for nanoscale sensin

Near-field energy transfer between a luminescent 2D material and color centers in diamond

Autor: Nelz, Richard, Radtke, Mariusz, Slablab, Abdallah, Kianinia, Mehran, Li, Chi, Xu, Zai-Quan, Bradac, Carlo, Aharonovich, Igor, Neu, Elke

Energy transfer between fluorescent probes lies at the heart of many applications ranging from bio-sensing and -imaging to enhanced photo-detection and light harvesting. In this work, we study F\"orster resonance energy transfer (FRET) between shallo

Report

Towards wafer-scale diamond nano- and quantum technologies

Autor: Nelz, Richard, Görlitz, Johannes, Herrmann, Dennis, Slablab, Abdallah, Challier, Michel, Radtke, Mariusz, Fischer, Martin, Gsell, Stefan, Schreck, Matthias, Becher, Christoph, Neu, Elke

We investigate native nitrogen (NV) and silicon vacancy (SiV) color centers in commercially available, heteroepitaxial, wafer-sized, mm thick, single-crystal diamond. We observe single, native NV centers with a density of roughly 1 NV per $\mu m^3$ a
