Engineering Physics of Superconducting Hot-Electron Bolometer Mixers [PDF]
IEEE Transactions on Terahertz Science and Technology, 2017 Superconducting hot-electron bolometers are presently the best performing mixing devices for the frequency range beyond 1.2 THz, where good-quality superconductor–insulator–superconductor devices do not exist. Their physical appearance is very simple: an

Vertically Aligned Few-Layered Graphene-Based Non-Cryogenic Bolometer
C, 2019 In this study, we report the photoresponse of vertically aligned few-layered graphene (VAG) upon infra-red (IR) irradiation at room temperature. Four probe measurements showed the current−voltage (I−V) characteristic of electrical switching ...

Comparison of Au and Pt Foils for an Imaging Bolometer
, 2010 In the imaging bolometer a thin metal foil converts plasma radiated power to infrared radiation measured by an infrared camera. Calibration of the foil provides information on its sensitivity, which is helpful in selecting the best foil material. In this

Microcalorimeter and bolometer model
Journal of Applied Physics, 2003 The standard nonequilibrium theory of noise in ideal bolometers and microcalorimeters fails to predict the performance of real devices due to additional effects that become important at low temperature. In this paper we extend the theory to include the most important of these effects and find that the performance of microcalorimeters operating at 60 mK
