Abstract

Macroscopic P3HT spherulitic crystals are grown in 25-nm-thick films via precise control of solvent swelling during polymer crystallization, which allow placement of transistor channels within single oriented crystal domains.Charge-transport anisotropy in the b?c (π-stacking & main chain) plane and the role of order?disorder grain boundaries are reported.
