THE ORGANIC THERMISTOR BOLOMETER

Canadian Journal of Research, 1946
When heat radiation falls on a thin sheet of cellophane painted on each side with aquadag, the electrical conductivity measured through the sheet changes sufficiently that the cellophane can be used as the sensitive element in a bolometer.

Complex impedance and equivalent bolometer, analysis of a low noise bolometer for SAFARI

Journal of Low Temperature Physics, 2012
Transition-edge-sensor (TES) bolometers are the chosen detector technology for the SAFARI Imaging Spectrometer on the SPICA telescope. For this mission, SRON is developing bolometers, each consisting of a TiAu TES that is weakly coupled to the thermal ...

A Colloidal Quantum Dot Thermistor and Bolometer. [PDF]

Adv Mater
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Dirac Surface-State Driven Broad Spectral Band Low Quantum Energy Photoresponse in Quaternary Topological BiSbSe₂Te. [PDF]

Adv Sci (Weinh)
Quaternary topological BiSbSe2Te are synthesized and demonstrates a broad spectral band photoresponse, ranging from infrared to terahertz and to millimeter waves, with a particular excellence on detection of low quantum energy terahertz photons. The observed photoresponse is attributed to the excitation of plasmonic nonequilibrium electrons originating

Bolometer operating at the threshold for circuit quantum electrodynamics [PDF]

Nature, 2020
Radiation sensors based on the heating effect of absorbed radiation are typically simple to operate and flexible in terms of input frequency, so they are widely used in gas detection1, security2, terahertz imaging3, astrophysical observations4 and ...

AI-Optimized Vanadium Oxide Multilayers for More Than 20-fold Enhancement in Bolometric Performance. [PDF]

Adv Sci (Weinh)
Machine‐learning‐optimized WxV1‐xOy multilayer thin films with graded doping achieve a high TCR (7.3 % K−1), reduced hysteresis, and low noise under CMOS‐compatible growth conditions. This approach overcomes the long‐standing trade‐off in microbolometers between linear response and performance, offering a universal bolometric parameter greatly enhanced

Folded-Dipole Antenna Geometrical Analysis for THz Microbolometer

IEEE Access, 2023
To improve the responsivity of terahertz (THz) antenna-coupled bolometer, heater (load) resistance has to be increased to suppress the thermal conduction and realize larger temperature rise of the thermistor.
