Convergence of electronic bands for high performance bulk thermoelectrics
TL;DR: It is demonstrated that it is possible to direct the convergence of many valleys in a bulk material by tuning the doping and composition, leading to an extraordinary zT value of 1.8 at about 850 kelvin.
Journal ArticleDOI
Thermopower in cobalt oxides
TL;DR: In this article, the thermopower in cobalt oxides generalizing the Heikes formula was studied and it was shown that the degeneracy, together with strong correlation of $3d$ electrons, causes the large energy consumption.
