| Abstract: | The research status of oxide thermoelectric material Ca_3Co_4O_9 is reviewed from the structure,preparation and doping.The effects of Ca-site and Co-site doping in Ca_3Co_4O_9 are briefly summarized.It is found that the effect of the Ca-site doping is much apparent than that of the Co-site doping.The results suggest that the Ca_3Co_4O_9 with appropriate doping will be one of thermoelectric materials with the most applicable prospect in moderate and high temperatures. |
