Abstract
Surface THz emission was observed from monolayer and bulk WSe2 via THz time-domain spectroscopy. Frequency and temporal spectra of the generated THz pulses were studied. Azimuthal dependencies of peak-to-peak THz amplitude were obtained for both layered WSe2. It was assumed that the generation of THz radiation in the bulk WSe2 occur due to the motion of photoexcited carriers and in the monolayer WSe2 due to nonlinear processes occurring after interaction with optical femtosecond pulses.
