This paper presents the experimental studies of the generation of terahertz radiation in periodic arrays of GaAs/AlGaAs core/shell nanowires via excitation by ultrashort optical pulses. It is demonstrated that terahertz emission occurs via excitation of photocurrent in the nanowires. The dynamics of photoinduced charge carriers is studied via the influence of an electron-hole plasma on terahertz radiation.
