We combine Laser Terahertz Emission Microscopy (LTEM) with terahertz time-domain nanoscopy in a near-field microscopy configuration. With this, we demonstrate how the two techniques provide complementary information about the sample.

We demonstrate depletion of terahertz emission from semiconductors by applying a DC bias between a substrate and an AFM probe operating in tapping mode. The depletion is strongly dependent on the probe tapping amplitude.
