Nitrogen-vacancy (NV) centers in diamond can be used as quantum sensors to image the magnetic field with nanoscale resolution. However, nanoscale electric-field mapping has not been achieved so far because of the relatively weak coupling strength between NV and electric field. Here, using individual shallow NVs, we quantitatively image electric field contours from a sharp tip of a qPlus-based atomic force microscope (AFM), and achieve a spatial resolution of ~10 nm. Through such local electric… Expand

Scanning Quantum Dot Microscopy.
A scanning probe technique that enables three-dimensional imaging of local electrostatic potential fields with subnanometer resolution is introduced and it is shown that because of its high sensitivity the technique can probe electro static potentials at large distances from their sources, which should allow for the imaging of samples with increased surface roughness.
