Description
Summary: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_{\mathrm{R}} ) is approximately a linear function of h_{\mathrm{abs}} , and the relationship between the Response bandwidth ( BW_{\mathrm{R}} ) and h_{\mathrm{abs}} has been given in this work.
