Abstract
Using <italic>ab initio</italic> methods, we predict α-Bi <sub>2</sub> Sn <sub>2</sub> O <sub>7</sub> to have an ultra-low lattice thermal conductivity at room temperature due to the high density of phonon scattering events, which makes it a potential earth-abundant n-type low temperature thermoelectric.
