Application of a Transparent Conductive Substrate with an Atomically Flat and Stepped Surface to Lateral Growth of an Organic Molecule: Vanadyl Phthalocyanine

Authors


Abstract

The lateral growth of an organic molecule on a transparent conductive substrate—important for molecular electronics—is demonstrated using vanadyl phthalocyanine (VOPc) on epitaxial indium tin oxide (ITO) film with an atomically flat and stepped surface. The occurrence of two-dimensional lateral growth is proved by the heights of the square-shaped domains of VOPc (see Figure) stacked parallel to the ITO substrate.
