| Popis: | We report $^{209}\mathrm{Bi}$ nuclear magnetic resonance spectra in nanowires and single crystals of ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$. Crystals were powdered to simulate the random orientation of the nanowires, and the spectra are compared with theoretical expectations derived via an orientational study of a single crystal. The nanowire spectra are consistent with the randomly oriented powders; however, we find an unusual suppression of signal intensity as a function of field orientation that may be associated with screening by surface currents. |
