Abstract
Spintronic Terahertz Emitters
In article number 2400064, Mathias Vanwolleghem and co-workers experimentally demonstrate a close to 100-fold improvement of the power efficiency of inverse spin Hall emitters by maximizing the impact of the electromagnetic environment of the nanometric emitter. As a result, by moving from a basic emitter on a bare substrate to one functionalized by a resonant crystal cavity and an impedance matched emitting substrate, the emitted THz field pulses can reach several MV/cm peak strengths without any echo behavior.
