摘要: We consider the classical limit for density of states an electron in a disordered one-dimensional chain. The low energy tail is analytically studied and we evaluate thermodynamical properties this system. For Boltzmann distribution heat capacity grows when disorder increases. On other hand quantum case, corresponding to Fermi-Dirac statistic, diminishes
