Classical percolation theory is concerned with the onset of geometrical connectivity and accompanied electrical in disordered systems. It was found, however, that many systems, such as various composites, onsets are not simultaneous correlation between them depends on physical processes tunneling. The difference above two types systems consequences for transport properties latter composites have been largely ignored past. application scanning local probe microscopies some recent theoretical developments enabled a better understanding their sometimes "strange" behavior bona fide In this review we consider issues manifestation three systems: Carbon Black–Polymer metal–insulator cermets hydrogenated microcrystalline silicon.
