Abstract
A pyroelectric-field effect electromagnetic radiation detector is comprised of a semiconductor body having opposed major surfaces. First and second electrodes are spaced apart from each other in ohmic contact with said semiconductor body to form a conductive channel in said body between said electrodes. A pyroelectric body having opposed major surfaces substantially normal to a polar axis thereof is positioned with one said major surface in intimate contact with and preferably electrostatically bonded to a major surface of said semiconductor body at least between said electrodes, and polarized therethrough substantially normal to said opposed major surfaces at least between said first and second electrodes. A gate electrode capable of absorbing radiation to be detected is also positioned adjacent said pyroelectric body at least between said electrodes. Alternatively, the semiconductor and pyroelectric bodies may be provided by a single body having both pyroelectric and semiconductor properties.
