Shot noise in mesoscopic transport through localised states

We show that shot noise can be used for studies of hopping and resonant tunnelling between localised electron states. In hopping via several states, shot noise is seen to be suppressed compared with its classical Poisson value SI = 2eI (I is the average current) and the suppression depends on the di...
