D08–Numerical simulation on the effect of the thickness of the absorbing layer on the spectral response characteristics for GaAs-based blocked impurity band (BIB) terahertz detectors

The effect of the thickness of the absorbing layer on the spectral response characteristics for Gallium Arsenide (GaAs) blocked-impurity-band (BIB) terahertz detector has been investigated in detail. It is found that Response bandwidth (BW_R) is approximately a linear function of h_Abs, and the relationship between the Response bandwidth (BW_R) and h_Abs has been given in this work.
