Terahertz emission from transient currents and coherent phonons in layered MoSe${}_2$ and WSe${}_2$

Jessica Afalla, Joselito Muldera, Semmi Takamizawa +4

Terahertz (THz) time-domain emission spectroscopy was performed on layered 2H-MoSe2 and 2H-WSe2. The THz emission shows an initial cycle attributed to surge currents and is followe…
