Abstract :
We combine ultrafast multi-terahertz spectroscopy and near-field microscopy to achieve sub-wavelength spatial (~15 nm) and sub-cycle temporal (~9 fs) resolution. We apply our novel system to photoexcited InAs nanowires and resolve femtosecond carrier dynamics - spatially, temporally and spectrally.
