Abstract: The nonlinear accumulation of the photogenerated electrons in high field biased
SI-GaAs has been defined as photo activated charge domain (PACD). The transient transport
dynamics of the PACD is investigated. The result shows that the PACD, working as a reverse gun
dipole domain when biased electric field much higher than 4 kV/cm, and the reverse mode of the
PACD could dominate the electric field shielding by its main electric field ultrafast and
exponential rising against the bias field. Such mechanisms could play an important role in GaAs
THz antenna, GaAs photoconductive semiconductor switch, and the other ultrafast GaAs devices.
