Nanoscale electric field sensing via the Stark effect of a single NV center in diamond — •Helmut Rathgen1, Florian Dolde1, Tobias Nöbauer2, Fedor Jelezko1, and Jörg Wrachtrup113. Physikalisches Institut, Uni Stuttgart — 2Atom Chip Group, TU Wien

We measure the Stark effect of a single Nitrogen vacancy center in diamond, and demonstrate its capability as a nanoscale electric field sensor. High sensitivity towards slowly oscillating electric fields is reached through coherent refocussing of the electron spin, following Hahn-echo and Carr-Purcell-Meiboom-Gill (CPMG) scheme. Experimental data of the Stark effect is confronted with current model Hamiltonians of the NV center. A highly local (nm scale) electric field measurement is enabled by using NV-doped diamond nano crystals, paving the way to in situ biological field sensing applications.
