Abstract
An essential component of far-infrared (FIR) heterodyne radiometers being developed1,2 for investigations of extraterrestrial molecular species (e.g., H2) is a wideband photomixer. Photoconductors are very attractive for this application as they operate at much lower electric fields than photodiodes, which have limited wideband performance in the FIR because of tunneling.3 Even in the case of photoconductors small electrode separations are necessary to minimize the electric field (and carrier velocity) needed to achieve high photoconductive gain at high frequencies. The interdigitated-electrode (IDE) structure enables both small electrode separations and active areas large enough for efficient detection.
