Abstract: This report describes the highlights and summary of the year 2, quarter four (Y2Q4) progress for the 6.2 project "Improved Sensitivity Low-Cost Uncooled IR Detector Focal-Plane Arrays."This work occurred during the January 2010–May 2010 time period. The program goals for Y2Q4 corresponded to the continued expansion of our barium titanium oxide (BaTiO3) nanomaterial synthesis capabilities and deposition methods; laser-induced pyroelectric phase conversion studies and nanoscale characterization of the pyroelectric activation process; and fabrication of infrared (IR) test heterostructures for pyroelectrical analysis, along with the development of a technique for generating the requisite IR absorbing layer.
