Thermoelectric transport in the layered Ca${}_3$Co${}_{4-x}$Rh${}_x$O${}_9$ single crystals

Yusuke Ikeda, Kengo Saito, Ryuji Okazaki

We have examined an isovalent Rh substitution effect on the transport properties of the thermoelectric oxide Ca${}_3$Co${}_4$O${}_9$ using single-crystalline form. With increasing Rh c…
