Interface interaction of transition metal phthalocyanines with strontium titanate (100)
We study interface properties of CoPcF(x) and FePcF(x) (x = 0 or 16) on niobium-doped SrTiO(3)(100) surfaces using mainly X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. For all studied molecules, a rather complex, bidirectional charge transfer with the oxide substrate w...

description | We study interface properties of CoPcF(x) and FePcF(x) (x = 0 or 16) on niobium-doped SrTiO(3)(100) surfaces using mainly X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. For all studied molecules, a rather complex, bidirectional charge transfer with the oxide substrate was observed, involving both the macrocycle and the central metal atom. For molecules of the first monolayer, an electron transfer to the central metal atom is concluded from transition metal 2p core level photoemission spectra. The number of interacting molecules in the first monolayer on the oxide surface depends on the central metal atom of the phthalocyanine, whereas the substrate preparation has minor influence on the interaction between CoPc and SrTiO(3)(100). Differences of the interaction mechanism to related TiO(2) surfaces are discussed. |
