Paper Abstract
We report the first observation of coherent plasmon emission of THz radiation from arrays of semiconductor
nanowires. The THz signal strength from InAs nanowires is comparable to a planar substrate, indicating the
nanowires are highly efficient emitters. This is explained by the preferential orientation of plasma motion to
the wire surface, which overcomes radiation trapping by total-internal reflection. Using a bulk Drude model,
we identify the average donor density and mobility in the nanowires in a non-contact manner. Contact IV
transconductance measurements provide order of magnitude agreement with values obtained from the THz
spectra.
