Efficient electrical spin readout of NV^- centers in diamond — •Florian M. Hrubesch, Georg Braunbeck, Felix N. Hartz, Martin Stutzmann, Friedemann Reinhard, and Martin S. Brandt — Walter Schottky Institut and Physik-Department, Technische Universität München

Using pulsed photoionization the coherent spin manipulation and echo formation of ensembles of NV^- centers in diamond are detected electrically realizing contrasts of up to 17 %. The underlying spin-dependent ionization dynamics are investigated experimentally and compared to Monte-Carlo simulations. This allows the identification of the conditions optimizing contrast and sensitivity which compare favorably with respect to optical detection [1].
