摘要
We describe a transport model for ordered polymer semiconductors that considers the physical and electronic structure, including the effects of hole delocalization in ordered lamella, grain boundary structures, a two-dimensional density of states, and percolation effects related to transport dimensionality. Simple model calculations are compared to experiments on regioregular polythiophene.
