摘要：

We present a drift-diffusion modeling of the electric-field profile in semi-insulating n-GaAs detectors accounting for hot-carrier dynamics and the associated kinetics of electrical active traps. From the fitting of the detector active thickness we infer unambiguous evidence of a field-enhanced capture cross section from the two deepest electron traps we attribute to EL2 and EL3 centers.
