| 中文摘要 | We report measurements of electrical resistivity, thermopower and thermal conductivity for a series of high-textured Ag-doped and Ag-added Ca(3)Co(4)O(9+delta) ceramic specimens. The results show that variable range hopping transport behaviour of the system transforms from two-dimensional to quasi-three-dimensional with Ag addition, which is isotropic to a certain extent. The thermoelectric (TE) performance of Ca(3)Co(4)O(9+delta) is improved effectively by Ag(+) doping or/and Ag addition. The Ca(2.7)Ag(0.3)Co(4)O(9+delta)/Ag(0.3) composite exhibits quite a respectable room temperature ZT value of 0.1, suggesting that such a composite is a promising candidate for p-type room temperature TE cooling application. |
