Nanoscale Scanning Diamond Magnetometer вђ Spin Physics Eth Zurich The ability to perform nanoscale electric field imaging of elementary charges at ambient temperatures will have diverse interdisciplinary applications. while the nitrogen vacancy (nv) center in diamond is capable of high sensitivity electrometry, demonstrations have so far been limited to macroscopic field features or detection of single charges internal to the diamond itself. in this work, we. Many applications of nv based magnetic sensing techniques have been proposed and demonstrated ever since, such as the magnetic imaging using an array of spins in diamond in 2010 , the nanoscale imaging accomplished by combining a single nitrogen vacancy with atomic force microscopy (afm) , the sensing of a mechanical resonator in 2012 , the sensing of a static vector magnetic field in 2013. We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the quantum diamond microscope (qdm). the qdm employs a dense layer of fluorescent nitrogen vacancy (nv) color centers near the surface of a transparent diamond chip on which a sample of interest is placed. nv electronic spins are coherently probed with microwaves and optically. Combining the intrinsic c 3 ν symmetry of diamond crystals and multiple frequency excitation technique, we can directly measure frequency modulated optically detected magnetic resonance ( odmr ) spectra for three different nv orientations and then obtain the zeeman splittings and the center frequency movement of the electron spin. an artificially generated underlying external magnetic.

This is achieved by measuring stark shifts in the nv spin resonance due to ac electric fields. we demonstrate a near single charge sensitivity of η e = 5.3 charges √hz and subelementary charge. This is achieved by measuring stark shifts in the nv spin resonance due to ac electric fields. we demonstrate a near single charge sensitivity of e = 5.3 charges hz and subelementary charge detection (0.68e). this proof of concept experiment provides the motivation for further sensing and imaging of electric fields using nv centers in diamond.
