DOI: 10.1002/adfm.202311217
Abstract: An ideal thermoelectric material requires the multi‐valley and strong dispersion band structure, for relieving the competition between thermopower and electrical conductivity, whereas the two features barely coexist in natural compounds. Here, the significantly improved thermoelectric… read more here.
