Abstract:
Analytical expressions of generalized Einstein relation for co-doping organic semiconductors, namely, the diffusivity–mobility ratio, are presented. Numerical calculations have been performed to analyze the dependences of D/μ on the various parameters of the Gaussian distribution density of states. The results show that the D/μ ratio for co-doping organic semiconductor deviates significantly from traditional Einstein relation and there exist two peaks in its dependence on the carrier concentration. Meanwhile, the value of generalized Einstein relation strongly depends on the doping level, orbital energy, and the dopants.
