Abstract
Conductance spectra of doped silicon nanowire (SiNW) arrays were measured from 0.5 to 50 GHz at temperatures between 4 and 293 K. For arrays consisting of 11 to >10 4 SiNWs, the conductance was found to increase with frequency as f s, with 0.25 < s < 0.45, consistent with behavior found universally in disordered systems. A possible cause is disorder from Si/SiO x interface states dominating the conductance due to the high surface-to-volume ratio of the nanowires.
