Electron Spin Echo Studies of the Nitrogen-Vacancy Center in Diamond Using the X-band Bruker 380E Pulsed EPR Spectrometer
EMSL Project ID
2189
Abstract
Recently, the Naval Research Lab has launched a general effort to investigate the spin dynamics properties of semiconductors with the long term hope of developing solid state technologies for quantum memory and quantum computing. As part of this effort, our group has focused on measuring spin coherence lifetimes and better understanding decoherence mechanisms in solids. The nitrogen-vacancy center in diamond has proven to be a particularly valuable subject. It has served as a useful model center for developing experimental techniques, and has increasingly proven to be scientifically interesting in its own right. It consists of a substitutional nitrogen next to a vacancy. These centers are created with high energy radiation followed by thermal annealing. , Steve Rand of the University of Michigan lent us the sample used in this study. It is a Sumitomo diamond (1.7 4 3.5 4 3.5 mm) which was electron irradiated and annealed; the total nitrogen concentration is 200 ppm, and the concentration of N-V centers is roughly 20 ppm (1 7 ppm).
