Abstract
The experimental results on the effect of an electron-hole plasma on the THz generation in GaAs NWs grown by MOVPE are presented. It is shown that the dynamics of photoexcited charge carriers in nanowires is determined by the transport of charge carriers - electrons and holes and by the capture time of electrons and holes onto the surface levels. The dependence of initial fall time of THz emission on the intensity of the pump can be accounted for by a theory based on majority-carrier flow. The characteristics time obtained can be used to determine the momentum relaxation time of the electrons.
