Nanodiamonds manipulation with AFM at nanoscale — •Yan Liu, Alexander Kubanek, and Fedor Jelezko — Institut für Quantenoptik, Universität Ulm

Nanodiamonds (ND) embedded with optically active colour centres have important applications. They are now widely used as bio-imaging makers at different wavelengths. in addition, they are excellent platforms for quantum optics study. Here we show the technique of manipulating nanodiamonds at nanoscale. Our experimental setup is the combination of AFM and a confocal fluorescence microscope also incorporated with synchronized microwave source, and it allows us to study the sizes of NDs, fluorescence properties and spin properties of negatively charged nitrogen vacancy colour centres in the NDs. Besides that, we can do repositioning with accuracy of about 20 nm and orientation flipping of the NDs using contact mode of the AFM. The results promote further studies on dipolar coupling of single photon emitters and spin-spin coupling of quantum platforms in different NDs, engineering integrated quantum optical circuits, etc.
