Abstract
Embodiments of the invention include methods and materials for preparing organic semiconducting layers, for example one used in an organic semiconductor device including a substrate with a nanostructured surface and a polymeric semiconductor film overlying the nanostructured surface. Aspects of the invention use capillary action to modulate polymer chain self-assembly on a surface and unidirectional alignment at a critical buried interface where charge carriers migrate between a dielectric and the polymer. By controlling the properties of the surfaces upon which polymers are disposed, artisans can enhance the transistor saturated mobilities of conjugated polymers.
