摘要：

In this chapter we present some useful concepts developed to describe theoretically electrical conduction in disordered organic materials such as molecularly doped and conjugated polymers and organic glasses. In such systems electrical conduction is due to incoherent hopping of charge carriers between localised states. We focus on the dependences of the conductivity and the carrier drift mobility on the concentration of localised states, concentration of carriers, temperature and electric field.
