摘要	We report measurements of electrical resistivity, thermopower and thermal conductivity for a series of high-textured Ag-doped and Ag-added Ca3Co4O9+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 Ca3Co4O9+delta is improved effectively by Ag+ doping or/and Ag addition. The Ca2.7Ag0.3Co4O9+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.
