abstract = {We introduce a scanning probe technique that enables
three-dimensional imaging of local electrostatic potential
fields with subnanometer resolution. Registering single
electron charging events of a molecular quantum dot attached
to the tip of an atomic force microscope operated at 5 K,
equipped with a qPlus tuning fork, we image the quadrupole
field of a single molecule. To demonstrate quantitative
measurements, we investigate the dipole field of a single
metal adatom adsorbed on a metal surface. We show that
because of its high sensitivity the technique can probe
electrostatic potentials at large distances from their
sources, which should allow for the imaging of samples with
increased surface roughness.},
