Nanoscale Probe of Magnetism Based on Artificial Atoms in Diamond
Abstract
This final report details our lab's accomplishments on nanoscale magnetic sensing using a nitrogen-vacancy (NV) center in diamond. Significant accomplishments funded by this award include 1) characterization of the surface induced decoherence with shallow, depth calibrated NV spins exhibiting long coherence times (accepted to PRL). 2) Construction of a combined atomic force microscope (AFM) and confocal microscope with 1 nm position stability. 3) The formation of high-quality factor single-crystal diamond mechanical resonators with integrated nanowire tips. 4) The formation of high-quality NV centers via chemical vapor deposition diamond growth with nitrogen delta-doping and the development of techniques such as patterned transmission electron microscope irradiation and patterned 12C implantation to form localized NV centers with long coherence times. 5)Scanned probe detection of a nanoscale volume of Gd3+ ions attached to a scanning tip using relaxation imaging. 6) Detection of a nanoscale volume of nuclear spins using a single spin in bulk diamond.
