A semiconductor YBaCuO microbolometer for room temperature IR imaging
TL;DR: In this article, the characteristics of infrared microbolometer arrays utilizing semiconducting YBaCuO and operating at room temperature are presented. And the spectral response was found to be uniform over a range of 1-12 /spl mu/m.

TL;DR: In this article, the authors explored the application of the semiconducting phases of YBaCuO thin films as a bolometer for uncooled infrared detection, and the bolometer figures of merit, responsivity, and detectivity were calculated from the measured temperature coefficient of resistance (TCR) and the inherent noise characteristics of the temperature sensing element.

Micromachined YBaCuO capacitor structures as uncooled pyroelectric infrared detectors
TL;DR: In this article, pyroelectric infrared detectors based on semiconducting Y-Ba-Cu-O have been investigated, with a wide range of values of the values with the maximum close to 20μC/cm2

Semiconducting YBaCuO thin films for uncooled infrared bolometers
TL;DR: In this article, the performance of semiconducting YBaCuO thin-film thermometers on silicon for uncooled bolometric applications was evaluated and it was shown that these thermometers can reveal a change in resistance with respect to temperature (dR/dT) as high as 8.2×103 Ω/K at T=294 K and the temperature coefficient of resistance as higher as 3.1% K−1 over a 60 K range around room temperature which implies an excellent bolometric response.
