The realization of a commercially viable, thin-film uncooled pyroelectric detector has been the focus of research for several years. As part of this effort we show that a conventional metallic electrode system (typically Pt) can be replaced with a conductive oxide such as La(x)Sr(1-x)CoO(3) (LSCO). In addition to being crystallographically compatible with the lead-based pyroelectric oxides such as Pb(0.9)La(0.1)Ti(0.975)O(3) (PLTlO) LSCO is also chemically compatible which aids in reducing the ...
Infrared absorbing air-bridge structures are anticipated to be used in the next generation of ferroelectric uncooled infrared detectors. These structures will consist of resonant cavities with an absorbing bridge element, which contains the ferroelectric detector and the contact electrodes. An oxide electrode is preferable to a metallic electrode, because the metallic electrode reflects too much of the incoming radiation at reasonable thickness. For this paper, spectral transmission and reflection of ...
