Abstract

Site-selective anisotropic growth of perylene film is achieved by using a striped Langmuir–Blodgett (LB) monolayer as an alignment layer. The stripes significantly increase the grain size along the stripe direction due to increased diffusion length. By controlling the grain boundaries and the molecular alignment, a mobility anisotropic ratio of ∼10 for the current flow parallel and perpendicular to the stripes has been observed.
