ABSTRACT
We study the direct response of a superconducting Nb hot-electron bolometer mixer centered at 2.5 THz that incorporates an Au/SiO[sub 2]/Al microstrip transmission line. The direct response is studied using a Fourier transform spectrometer. We find a peak response at a frequency of 2.1 THz, which is 20% lower than predicted based on a model that neglects the inductance effect in the microbridge. © 2001 American Institute of Physics.
