Efficient electrical spin readout of NV- centers in diamond
arXiv:1608.02459 · doi:10.1103/PhysRevLett.118.037601
Abstract
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.
