  • Single Molecular Adsorption of Terbium(III) Bis-phthalocyaninato (TbPc<sub>2</sub>) Governed by Two Surface Reconstructions of Perovskite Type SrVO<sub>3</sub> Epitaxial Ultrathin Film

Description

Using low temperature scanning tunneling microscopy (STM), we observed a single molecule magnet, Tb3+ double decker molecule TbPc2 (Pc = phthalocyaninato), adsorbed on a perovskite type transition metal oxide SrVO3 ultrathin film. TbPc2 molecules adsorbed intact and flat on two surface reconstructions of SrVO3, (2–√×2–√)-R45° and (5–√×5–√)-R26.6°, with different configurations. High resolution STM images revealed that the adsorption configurations were governed by the adatom structure of each surface reconstruction according to the proposed adsorption configurations.
