Research Abstract

Graphoepitaxy of organic molecules was investigated. Periodic microgrooves were fabricated on the substrate surface by electron beam lithography and organic semiconductor thin films were grown on the surface by vacuum deposition. In-plane oriented growth was observed. It was also found that the in-plane orientation can be changed by surface modification of the substrates ; this phenomenon is peculiar to organic systems and relates to the mechanism of organic graphoepitaxy.
