Water has a higher … Web17 de nov. de 2016 · The density of states really measures the number of states in a small energy range. Therefore, flatter bands will have more states over a small energy range compared to a highly dispersive band. Said another way, if the orbitals are pretty localized, the effective mass is higher, leading to a large number of states over a small energy …
