Hot electron bolometer sensors for millimetre-wave and terahertz wave detection

[摘要] ENGLISH ABSTRACT: The design and simulation of hot electron bolometer sensors for the detectionof millimeter and terahertz wave radiation is presented. These devices can beused for the formation of images or for spectroscopy in these frequency ranges.Many molecules resonate and have absorption spectra over these ranges, allowingfor the identi cation, non-destructively and at a distance, of the constitutionof many di erent materials. The penetrating ability of the radiationmakes mm-wave and THz wave detectors ideal for security imaging. The designand simulation of these devices predicts performance as mixers and asinterferometers. Manufacturing processes used while fabricating these thin lm devices are outlined and experimental results are reported.
