Materials Research of Perovskite Thin Films for Uncooled Infrared (IR) Detectors

This report describes the highlights and summary of the year two, quarters two and three progress for the 6.2 project Improved Sensitivity Low-Cost Uncooled IR Detector Focal-Plane Arrays. This work occurred during the August 2009 January 2010 time period. The program goals for year 2-quarters 2&3 corresponded to the continued expansion of our BaTiO3 nanomaterial synthesis capabilities and deposition methods, laser-induced pyroelectric phase conversion studies and nanoscale characterization of the pyroelectric activation process, and fabrication of IR test heterostructures for pyroelectrical analysis, along with the development of a technique for generating the requisite IR absorbing layer.
