| Outline of Final Research Achievements |
Effect of dipole moments of organic molecules on the transfer time of excited charge across molecule/metal-oxide junctions has been verified. Photoelectron spectroscopy, X-ray absorption spectroscopy and core-hole clock spectroscopy were utilized to examine the properties of the junctions between shuttle cock-type phthalocyanine films and strontium titanate surfaces. The charge transfer time from phthalocyanine to the oxide surface tends to be shorter if phthalocyanine has a larger dipole moment. However, the interaction strength and the energy-level alignment at the interface affect more drastically the transfer time.
