Ultrabroadband High Photoresponsivity at Room Temperature Based on Quasi‐1D Pseudogap System (TaSe4)2I

Advanced Science, Volume 11, Issue 7, February 16, 2024.
A new type of photodetector based on PG system (TaSe4)2I is proposed, and high photo responsivity covering ultrabroadband wavelength range (UV to LWIR) including mechanism are revealed in proof‐of‐concept nanoribbon devices. The achieved photodetection performance is superior than most of other low‐dimensional materials.

Superconducting Cold-Electron Bolometers with JFET Readout for OLIMPO Balloon Telescope

Journal of Physics: Conference Series, 2006
The OLIMPO experiment is a 2.6 m balloon-borne telescope, aimed at measuring the Sunyaev- Zeldovich effect in clusters of Galaxies. OLIMPO will carry out surveys in four frequency bands centered at 140, 220, 410 and 540 GHz. The detector system consists of four bolometer arrays and incorporates new detector technologies that are potential candidates ...

A parallel/series array of superconducting cold-electron bolometers with SIS' tunnel junctions [PDF]

SPIE Proceedings, 2008
A novel concept of the parallel/series array of Cold-Electron Bolometers (CEB) with Superconductor-Insulator-Normal (SIN) Tunnel Junctions has been proposed for matching with JFET readout. The current-biased CEBs are connected in series for DC and in parallel for HF signal.

Multichroic seashell antenna with internal filters by resonant slots and cold-electron bolometers

Superconductor Science and Technology, 2019
We have developed and realized a novel multichroic seashell antenna with internal bandpass filters by resonant slots and cold-electron bolometers (CEB). Slots and CEBs are connected by coplanar waveguides (CPW) instead of microstrip lines to realize the most reliable single-layer technology.

Strong Electron Self-Cooling in the Cold-Electron Bolometers Designed for CMB Measurements

Journal of Physics: Conference Series, 2018
We have realized cold-electron bolometers (CEB) with direct electron self-cooling of the nanoabsorber by SIN (Superconductor-Insulator-Normal metal) tunnel junctions. This electron self-cooling acts as a strong negative electrothermal feedback, improving noise and dynamic properties.
