Space-Time mapping of terahertz-induced electron field emission

We present simulations and experiments showing how THz induced electron field emission from gold antennas can be mapped indirectly in space and time. Our simulations predict the spatiotemporal electron distribution after single-cycle THz-induced field emission. Two different experiments validate this through a time-accumulated, spatial electron mapping due to both short- and long-time irradiation with THz transients.
