Efficient thermoelectricity in Sr${}_2$Nb${}_2$O${}_7$ with energy-dependent relaxation times

Giulio Casu, Andrea Bosin, Vincenzo Fiorentini

We evaluate theoretically the thermoelectric efficiency of the layered perovskite Sr${}_2$Nb${}_2$O${}_7$ via calculations of the electronic structure and transport coefficients within d…
