Characterizing the local internal environment surrounding solid-state spin defects is crucial to harnessing them as nanoscale sensors of external fields. This is especially germane to the case of defect ensembles which can exhibit a complex interplay between interactions, internal fields, and lattice strain. Working with the nitrogen-vacancy (NV) center in diamond, we demonstrate that local electric fields dominate the magnetic resonance behavior of NV ensembles at a low magnetic field. We…

Nanoscale Vector Electric Field Imaging Using a Single Electron Spin.
A near single-charge sensitivity of ηe = 5.3 charges/√Hz and subelementary charge detection (0.68e) is demonstrated by measuring Stark shifts in the NV spin-resonance due to AC electric fields, which provides the motivation for further sensing and imaging of electric fields using NV centers in diamond.
