W. Zerner, Martin P., Directional decay of the Green's function for a random nonnegative potential on Z\spd, Annals of applied probability , 8(1), 1998, pp. 246-280
We derive a shape theorem type result for the almost sure exponential decay of the Green's function of ..+V, where the potentials V(x),x.Zd are i.i.d. nonnegative random variables. This result implies a large deviation principle governing the position of a d-dimensional random walk moving in the same potential.
