Ultrafast dynamics of free carriers in low-temperature grown GaAs was studied using time-domain terahertz emission spectroscopy. The subpicosecond free-carrier lifetime was determined for a set of annealed samples with different growth temperatures (175-250 C), the carrier mobility was also estimated.
