  • We use above-band-gap optical excitation, via a 1047-nm laser, to hyperpolarize the $^{31}\mathrm{P}$ spins in low-doped (${N}_{D}=6\ifmmode\times\else\texttimes\fi{}{10}^{15}\phantom{\rule{0.16em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$) natural abundance silicon at 4.2 K and 6.7 T, and inductively detect the resulting NMR signal. The 30-kHz spectral linewidth observed is dramatically larger than the 600-Hz linewidth observed from a $^{28}\mathrm{Si}$-enriched silicon crystal. We show that the… CONTINUE READING
