High <i>D</i>* Pyroelectric Polyvinylfluoride Detectors

Abstract

Polyvinylfluoride plastic films exhibit a normalized detectivity, D* (500 K, 1, 1), of 3×108 cm Hz1/2/W. This value for the infrared-detector figure of merit is close to the highest available from other pyroelectric materials. A pyroelectric coefficient of 1 nC/cm2K was obtained from the optical response, and a material figure of merit of 1.3×10−9 C cm/J was determined.
