Abstract
Effective pyroelectric coefficients as large as 5 mu C/cm(2) degrees C , with peak responsivities at approximately 50 degrees C, were obtaine d from compositionally graded barium strontium titanate ferroelectric thin film devices formed on silicon using unbalanced magnetron sputter deposition. These effective pyroelectric coefficients are nearly two orders of magnitude larger than those observed from conventional pyroe lectric thin film ferroelectric detectors.
