Abstract

An evaluation of the pyroelectric properties of ferroelectric lead germanate Pb₅Ge₃O₁₁ in both single-crystal and ceramic form is presented. It is shown that the expected noise-equivalent power for lead germanate is similar to that of triglycine sulphate, and the voltage responsivity is slightly lower. The superior chemical and mechanical properties of lead germanate make it an attractive alternative for use in pyroelectric detectors.
