Giant effective pyroelectric coefficients from graded ferroelectric devices
F Jin, GW Auner, R Naik, NW Schubring… - Applied physics …, 1998 - pubs.aip.org
Effective pyroelectric coefficients as large as 5 C/cm2 C, with peak responsivities at
approximately 50 C, were obtained 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 pyroelectric thin film ferroelectric detectors.©
