Abstract
We study a penetration of an electron with high energy
through strongly disordered wire of length (a being the
localization length). Such an electron can loose, but not gain the energy,
when hopping from one localized state to another. We have found a
distribution function for the transmission coefficient . The
typical remains exponentially small in L/a, but with the
decrement, reduced compared to the case of direct elastic tunnelling:
. The distribution function
has a strong tail in the domain of anomalously high ; the average
is controlled by rare
configurations of disorder, corresponding to this tail.
