Abstract

Grain boundaries can be engineered in directionally oriented thin films of poly(3-hexylthiophene) report Alberto Salleo and co-workers on p. 1568. Charge-transport studies coupled with X-ray and AFM characterization indicate that intergrain transport is greatly facilitated when neighboring grains can be bridged by relatively straight polymer chains.
