NMR study of optically hyperpolarized phosphorus donor nuclei in silicon
P. Gumann, H. Haas, S. Sheldon +4
We use above-bandgap optical excitation, via a 1047 nm laser, to hyperpolarize the P spins in low-doped (N cm) natural abundance silicon at 4.2 K…
Inductive measurement of optically hyperpolarized phosphorous donor nuclei in an isotopically-enriched silicon-28 crystal
P. Gumann, O. Patange, C. Ramanathan +9
We experimentally demonstrate the inductive readout of optically hyperpolarized phosphorus-31 donor nuclear spins in an isotopically enriched silicon-28 crystal. The concentration…
Radical-free dynamic nuclear polarization using electronic defects in silicon
M. C. Cassidy, C. Ramanathan, D. G. Cory +2
Direct dynamic nuclear polarization of 1H nuclei in frozen water and water-ethanol mixtures is demonstrated using silicon nanoparticles as the polarizing agent. Electron spins at d…
Spin diffusion of correlated two-spin states in a dielectric crystal
G. S. Boutis, D. Greenbaum, H. Cho +2
Reciprocal space measurements of spin diffusion in a single crystal of calcium fluoride (CaF) have been extended to dipolar ordered states. The experimental results for the com…
Stochastic Resonance and Nonlinear Response by NMR Spectroscopy
L. Viola, E. M. Fortunato, S. Lloyd +2
We revisit the phenomenon of quantum stochastic resonance in the regime of validity of the Bloch equations. We find that a stochastic resonance behavior in the steady-state respons…
