TL;DR: An analytical mobility model based on percolation theory of hopping between localized states is obtained and this model is applied to the analysis of both the electric field dependence and the temperature dependence of the mobility.

TL;DR: In this paper, an analytical model describing hopping transport with traps is formulated on the basis of percolation theory, and the results show that the presence of a trap distribution with energy offset and width different from that of the intrinsic density of states does not change the basic phenomenology of hopping transport, as revealed by the temperature dependence of the conductivity at high temperature.

TL;DR: In this paper, an analytical model describing the effect of partially filled localized states on the concept of transport energy is presented, based on variable range hopping theory, and the results illustrate that at low enough temperature the partially-filled localized states in organic semiconductor systems play an important role on the transport energy.

TL;DR: In this paper, an analytical conductivity model based on the variable range hopping theory was proposed to explain the superlinear increase of the conductivity with doping, as well as the change in the conductivities of an organic semiconductor upon the doping ratio.
