Accepted manuscript on a novel method to measure time-resolved THz photoconductivity in the near-field

In this manuscript, we show proof-of-concept measurements on a GaAs film that was excited though a total internal reflection geometry. With this technique, we can obtain the photo-excited carrier dynamics and the THz photo-conductivity with a spatial resolution well below the THz diffraction limit. The manuscript entitled “Time-resolved terahertz time-domain near-field microscopy” has been published…
