Abstract: Through a three-way collaboration between the Institute for Collaborative Biotechnologies (ICB) at the University of California, Santa Barbara; The Aerospace Corporation; and the U.S. Army Research Laboratory, we investigated the use of a pyroelectric perovskite based material for a novel two-dimensional uncooled infrared focal plane array. Barium strontium titanate (BSTO) was chosen by the ICB as the perovskite material to be used due to its stable nanocrystals, which would allow a high quality, homogenous, crack-free film to be dispersed onto sensor readouts. This ferroelectric ceramic material, once transformed into the pyroelectric crystalline form, would be used as the active material in thermal imaging devices. An in-house process for the film deposition was developed for this purpose.
