Title

Transport Anisotropy and Percolation in Exciton Dynamics

Abstract

I discuss some applications of a recent dynamical theory of excitation transport for highly anisotropic disordered solids. Particular attention is paid to a discussion of anisotropic percolating lattice, for which the vanishing anisotropy of the diffusion tensor at the critical point is studied in some detail. It is predicted that systems which are very nearly 2-dimensional in the pure crystal limit exhibit a crossover to isotropic 3-dimensional transport in the neighborhood of the transition point. This could have important implication for anisotropic solids which have been interpreted in terms of isotropic model systems of reduced dimensionality.
