(a) Sweeping out of electrons under large biased electric field E for MCT-1 irradiated by sub-THz source at modulation frequencies of 1 KHz and 10 KHz. Biased E increases the electron concentration n, but reduces the injected electron concentration Δn by partially sweeping them out. (b) Photoconductance Δσ/σ and time constant td of the MSM structure for MCT-2 with smaller composition and gap distance at different biased electric field E irradiated by sub-THz source. Symbols: experimental data. Green line: theoretical fitting.
