Abstract
Small band gap topological insulators and Weyl semimetals show excellent TE properties. We identify two mechanisms (i) asymmetry in the electronic density of states caused by band inversion at an electronic topological transition and (ii) band convergence as the key to good TE behavior of these materials.
