The main results of our investigations are described covering the charge carrier transport in polyvinylcarbazole thin layers doped with monomer-like molecules N-vinylcarbazole. With the enhancement of the monomer concentration two steps are observed in the carrier mobility, the conductivity, and trapping properties. This behavior can be analyzed by the introduction of the transport network determined from the molecular superstructure of the polymer system by the introduction of the local hopping space. The fractal approached was used for the characterization of the transport network. We propose the introduction of transport tubes to describe the carrier transport in disordered systems.
