Thermoelectric transport of strained CsK${}_2$Sb: The role of electron velocities and scattering within extended Fermi surfaces

Øven A. Grimenes, G. Jeffrey Snyder, Ole M. Løvvik +1

In this first-principles study, we investigated the thermoelectric properties of the full-Heusler compound CsK${}_2$Sb at different compressive strains. This material exhibits a vale…
