Abstract
The Thermally Stimulated Depolarization Current (TSDC) of the
modified SBN ferroelectric ceramic system was studied. The TSDC
measurements show the pyroelectric peak for all compositions while a
second smaller peak at higher temperatures, possibly associated to
induced vacancy-impurity dipoles is also observed in all cases. The
second peak contribution was experimentally and mathematically
eliminated. The activation energies and infinite temperature relaxation
time of both processes are determined
