| Research Abstract |
Thermoelectric materials, which directly convert heat into electricity, were developed. In this study, it was found that Ba_3Co_2O_6(CO_3)_<0.7> showed a high power factor of about 1×10^<-3> Wm^<-1> K^<-2> (300 K). Ba_3Co_2O_6(CO_3)_<0.7> has Co-O one-demensional chains in its crystal structure, and the Co-O chains are key unit for developing high performance thermoelectric materials.
