Paper Abstract

Thermodynamics, physical nature and production mechanisms of polar states initiated by external nonscalar action in noncentral crystals are investigated. Spatially inhomogeneous heating of nonpolar piezoelectric crystals provides the means of producing new properties in crystals which do not exhibit these properties in the thermodynamically equilibrium state, creating artificial pyroactive media with controlled physical parameters. Theoretical and experimental explorations are aimed at the investigation of tertiary pyroelectric effect that has indicated potential for a solving problems of monitoring and registering intense laser radiation. A novel approach to the development of infrared pyroelectric sensors and devices on the basis of the proposed artificial pyroactive materials is formulated. Crystal quartz showing pyroactive properties under spatially inhomogeneous heating conditions is suggested as sensitive element for pyroelectric transmission type power sensors in visible and near IR-range of spectrum.
