N. Duan et al., THICKNESS DEPENDENCE OF HEAT TO ELECTRICAL ENERGY-CONVERSION AT THE F-RL-F-RH PHASE-TRANSITION OF PZT FERROELECTRIC CERAMICS, Journal of the Korean Physical Society, 32, 1998, pp. 1781-1783
A simple experimental setup used previously to investigate the power o
utput and the efficiency of PZT ferroelectric materials to convert ene
rgy from thermal to electrical, has been used to investigate their dep
endence on sample thickness and frequency. In addition to the usual th
ermal and electrical reIaxation times another (residual) relaxation ti
me is needed in order to describe the performance of Zr-rich PZT under
thermal cycling.
