Abstract

A well-ordered molecular arrangement is a necessary condition for “band transport” in molecular semiconductor materials, and thus it is important for donor-acceptor molecular junctions for applications in advanced organic optoelectronic devices. In this study, the heteroepitaxial growth of an acceptor material C₆₀ on a single-crystal (001) surface of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT), a representative high-mobility donor material, is demonstrated. Surface X-ray diffraction analysis indicated spontaneous alignment of the nearest-neighbor molecular direction of the C₆₀ crystallites uniquely to the a -axis of the DNTT.
