Abstract
This paper reviews the latest developments in pyroelectric devices for IR detection based on sol-gel derived ferroelectric thin films, highlighted by recent results from our laboratories. The optimization of sol-gel processing has led to ferroelectric films with pyroelectric coefficients as high as 200 nC/cm2-K. Some modeling results of the thin film devices, which aid in device design, are also discussed. At the film level, various factors such as chemistries, microstructures and processing conditions all affect the final pyroelectric properties of the films. At the device level, processing compatibility and device layout need to be taken into account to optimize fully the device performance.
