Enhanced high temperature thermoelectric characteristics of transition metals doped CaCoO by cold high-pressure fabrication

Yang Wang, Yu Sui, Xianjie Wang, Wenhui Su, and Xiaoyang Liu A series of Fe, Mn, and Cu doped CaCoO samples, Ca(Co,M)O (M=Fe, Mn, and Cu), were fabricated by cold high-pressure compacting technique. Their thermoelectric properties were investigated from room temperature up to 1000 K. The cold high-pressure compacting method is advantageous to increasing densi ... [J. Appl.
