Paper Abstract

The two-dimensional coherence function corresponding to positively charged polarons (“holes”) in poly(3- hexylthiophene) π-stacks is calculated based on a Holstein-style Hamiltonian which treats electronic coupling, vibronic coupling and disorder on equal footing. Assuming a model of isotropic site-energy disorder, the hole is found to be delocalized between 1-2 nm along the polymer chain and between 0.5-1 nm along the stacking axis.
