Resonant Photoemission Spectroscopy of Highly-Oriented-Coronene Monolayer using Photoelectron Momentum Microscope

抄録

Information of spatial and energy distribution of the electronic state described from the localized molecular orbitals is important to understand the electronic and optical properties of molecular materials. In this study, photoemission spectra of a highly-oriented-coronene monolayer on Au(111) were measured by a photoelectron momentum microscope (PMM) installed at the soft X-ray beamline BL6U of UVSOR-III synchrotron. Whole valence band mapping across wide momentum space and site-selective resonant photoemission spectroscopy of this system were demonstrated as a case study of the newly installed PMM apparatus.
