Systematic Study of Pyroelectricity. Light Scattering and Pyroelectricity in Ferroelectrics.

摘要

The results of two studies of pyroelectric materials are reported. In the first, a Raman scattering study of KNbO3, anomalous scattering is found which can be related directly to the dynamic disorder which has been invoked to explain the results of earlier x-ray and neutron scattering studies and which provides the starting point for the generalized molecular field theory of ferroelectricity proposed elsewhere by the authors. The second is an analysis of the physical properties of pyroelectric materials which determine their performance as vidicon targets.
