Responsivity and Noise Equivalent Power of a Single Cold-Electron Bolometer [PDF]

open access: yesApplied Sciences, 2021
We have developed a single-pixel capacitively coupled Cold-Electron Bolometer (CEB) and characterized it in the current-biased regime. The most attractive feature of the CEB is effective electron self-cooling of the absorber, which leads to a lower ...

Theoretical Investigation of Responsivity/NEP Trade-off in NIR Graphene/Semiconductor Schottky Photodetectors Operating at Room Temperature [PDF]

open access: yesApplied Sciences, 2021
In this work we theoretically investigate the responsivity/noise equivalent power (NEP) trade-off in graphene/semiconductor Schottky photodetectors (PDs) operating in the near-infrared regime and working at room temperature.

A Distributed Terahertz Metasurface with Cold-Electron Bolometers for Cosmology Missions

open access: yesApplied Sciences, 2021
We developed and tested a 2D periodic array of cold-electron bolometers arranged into a wideband frequency selective metasurface that absorbs more than 70% of the incident power in the frequency range 100–800 GHz.
