Soft X-ray photoelectron spectroscopy under real ambient pressure conditions
We have developed a measurement system for soft X-ray ambient pressure photoelectron spectroscopy at BL08U of NanoTerasu. An excitation light of 800 eV was introduced by a vacuum tube terminated with a SiN window. Photoelectrons were detected through a ϕ24 μ m aperture at the electron lens entrance...

| Summary: | We have developed a measurement system for soft X-ray ambient pressure photoelectron spectroscopy at BL08U of NanoTerasu. An excitation light of 800 eV was introduced by a vacuum tube terminated with a SiN window. Photoelectrons were detected through a ϕ24 μ m aperture at the electron lens entrance of a differentially pumped analyzer. The Au 4 f core-level spectra of a Au film were measured up to atmospheric pressure (1 bar) with He, to 1 bar with H _2 , and to 0.4 bar with N _2 . The system extends applications of operando experiments for the real functional materials. |
