Distribution of time constants for tunneling through a one-dimensional disordered chain

The dynamics of electronic tunneling through a disordered one-dimensional chain of finite length is considered. We calculate distributions of the transmission coefficient T, Wigner delay time tau(W), and the transport time tau(1) = T tau(W) The central bodies of these distributions have a power-law form, which can be understood in terms of the resonant tunneling through localized states.
