A new method to characterize electron scattering in solids is presented. This method is based on the concept of fractal geometry leading to a generalized walk. A criterion is presented to validate the applicability of this method. This method is applied to random walks with variable mean free path to validate it. Finally, this method is applied to the diffusion of incident electrons in solids of gold and carbon to characterize the transition between persistent and random walk processes describing the diffusion of the electrons in these materials.
