Abstract

alpha-Quaterthiophene thin films were grown on the {001} face of single crystals of tetracene by organic molecular beam epitaxy. The peculiar corrugation of the {001} surface of tetracene, its chirality, and its low symmetry give rise to two phases of the overlayer. The morphology-structure and epitaxial relations of these two phases are investigated on a local scale by atomic force microscopy and on a large scale by optical spectroscopy, revealing the orientation mechanisms driving the formation of this organic-organic heteroepitaxial system of semiconductors.
