Abstract
- The pyroelectric and dielectric bolometer properties of Sr modified BaTiO<subscript>3</subscript> ceramics were investigated for thermal IR detector applications. The (Ba<subscript>1−x</subscript>, Sr<subscript>x</subscript>)TiO<subscript>3</subscript> solid solution ceramics have been prepared by adding 10–40 at % SrTiO<subscript>3</subscript> to BaTiO<subscript>3</subscript> and with different sintering conditions and under dc fields. The relationships of processing parameters, microstructures, dielectric/pyroelectric properties and dc fields are discussed. And the “figures of merit” are compared between pyroelectric-type and dielectric bolometer-type IR sensors based on the experimental results. [ABSTRACT FROM AUTHOR]
