Enhanced electron correlation in rare-earth doped CaCoO

Yang Wang, Luxiang Xu, Yu Sui, Xianjie Wang, Jinguang Cheng et al. Thermoelectric and thermodynamic properties of a series of Ca-site rare-earth R doped CaCoO were investigated. For a fixed doping level, with the reduction in R radius, thermopower is found to gradually increase despite the carrier concentration remains unchanged. The scaling behavior between thermo ...
