Terahertz generation by GaAs nanowires [PDF]
2012 37th International Conference on Infrared, Millimeter, and Terahertz Waves, 2012 The results of investigation of terahertz generation in Al0.2Ga0.8As nanowires by the optical excitation of femtosecond pulses are presented. It is shown that the radiation is generated by excitation of photocarriers in nanowires. The time-resolved dynamics of photocarriers were studied by optical-pump terahertz generation-probe time-domain ...

Terahertz harmonic generation in graphene [PDF]
Applied Physics Letters, 2015 We show that charge carrier transport in graphene exhibits sharp resonances in the presence of spatially and temporarily modulated scattering. Resonances occur when the period of an applied a–c field corresponds to the time taken by quasi-ballistic carriers to drift over a spatial scattering period, provided the latter is shorter than the distance ...

Ultrafast carrier generation in Bi1-xSbx thin films induced by intense monocycle terahertz pulses [PDF]
EPJ Web of Conferences, 2019 Using terahertz-pump and terahertz-probe spectroscopy, we investigated terahertz-induced carrier generation processes in Bi1-xSbx thin films. The field dependence of the terahertz-induced transmittance change indicates distinct nonlinearity related to ...
