Ferroelectric Films for IR Focal Plane Array Storage Capacitors

Infrared radiation sensing has grown rapidly as both a military and commercial detection and measurement technique. Recently the sensitivity of infrared detection has been improved by the used of focal plane arrays which have the capability of imaging scenes of very low contrast by collecting radiation over long periods of time. This technique can be dramatically enhanced by the use of new materials which have the capability of extending the storage period for the electrical charge generated infrared radiation striking the detector. ATM of Danbury, CT has developed a new material that will be fabricated into the thin film form required for incorporation into infrared detectors during Phase I. Phase II will allow for the fabrication of both storage capacitors and prototype devices.
