Dielectric Properties of Pb5Ge3O11 Thick-Films Prepared by Rapid-Quenching

Thick-films of Pb5Ge3O11 with full density and thickness of 60μm were prepared by rapid-quenching. A pyroelectric detectivity of 107(cm⋅Hz1/2/W) was obtained, equwalent to that of a commercial infrared detector. Polarization reversal by applied voltage was very slow, indicative of a relaxation pheno...
