Enhanced Seebeck coefficient by a filling-induced Lifshitz transition in KxRhO2

Naoko Ito, Mayu Ishii, Ryuji Okazaki

We have systematically measured the transport properties in the layered rhodium oxide K${}_x$RhO${}_2$ single crystals ($0.5\lesssim x\lesssim 0.67$), which is isostructural to th…
