Ultrafast Dynamics of Spin Current and Electron Temperature in Spintronic Terahertz Emitters

open access: yesAdvanced Science, EarlyView.
This work quantifies optical‐pump‐induced THz transmission variations to reveal electron and lattice temperature dynamics and presents time‐resolved THz spectral maps for sub‐picosecond analysis. A 63 ± 8 fs time lag between THz emission and laser excitation is identified, serving as an intrinsic parameter limiting the upper frequency of spintronic THz

On the Theory of Plasma Waves

Proceedings of the Physical Society. Section B, 1956
Die folgende Theorie bezieht sich auf ein Plasma, für das eine stationäre Geschwindigkeitsverteilungsfunktion für die Elektronen existiert. Den Ausgangspunkt der Rechnung bildet die Boltzmannsche Fundamentalgleichung, in der der Stoßanteil vernachlässigt wird.
