摘要：
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 degreesC), the carrier mobility was also estimated. The influence of the growth temperature on the ultrafast carrier trapping is discussed. (C) 2001 American Institute of Physics.
