The Bethe lattice is exactly solvable in the limit where each lattice site has an infinite number of nearest-neighbors. In this limit it yields a semi-circular density of states in the conduction band. In which specific materials is it a good model for the electronic structure?

    $\begingroup$ Could you provide a bit more detail about the Bethe lattice or a link to a diagram, etc. Bethe was a genius, so there are a lot of things with similar names, haha $\endgroup$ Commented Mar 23, 2021 at 15:53

    $\begingroup$ This paper references some applications to amorphous materials. Maybe those references, or citations to that paper, could be a useful starting point. $\endgroup$
