a Geometrical structure diagram of the blue LED. b Multiplication factor determined by initial carrier density as well as number of impact ionizations as a function of the incident THz electric field strength. The theoretical calculation based on the Monte Carlo model can well explain the experimental results. c The waveform of a THz pulse with/without screening effect when incident field strength of 200 kV/cm. d Carrier density multiplication processes with 200 kV/cm and 100 kV/cm incident field strength, respectively. e The energy evolution of holes during the interaction with transmitted THz pulse under the condition in (d).
