Abstract
We have been measuring the bulk electrical and thermal properties of t he quantum ferroelectric KTa0.992Nb0.008O3 (KTN) in the interest of ma king a thermal sensor for a pyroelectric microcatorimeter. The pyroele ctric coefficient and specific heat of KTN as a function of temperatur e and electric field are given. The measurements indicate that a thin film detector with the same pyroelectric coefficient as that found in our sample would in principle be able to operate in a phonon noise lim ited regime over a wide bandwidth.
