| 英文摘要 | effect of crystal size distribution on thermoelectric performance of lanthanum-doped strontium titanate (la-srtio3) ceramics are investigated in this study. thermoelectric performance measurement, coupled with microstructure studies, shows that the electrical conductivity strongly depends on the crystal size, potential barrier on the grain boundary and porosity. meantime, because the average potential barriers height are increased along with the reduction of crystal size, the seebeck coefficients are increased by energy filtering effect at the large number of grain boundaries. as a result, by controlling of crystal size distribution, zt value of la-srtio3 is improved. |
