Thermoelectric calculations of ring-shaped bands in two-dimensional Bi${}_2$Te${}_3$, Bi${}_2$Se${}_3$ and Sb${}_2$Te${}_3$: a comparison of simple scattering approximations

Cameron Rudderham, Jesse Maassen

Materials with ring-shaped electronic bands are promising thermoelectric candidates, since their unusual dispersion shape is predicted to give large power factors. While previous c…
