Energy-filtered X-ray photoemission electron microscopy and its applications to surface and organic materials
Energy-filtered X-ray photoemission electron microscopy (EXPEEM) is a new surface chemical imaging method that combines X-ray photoelectron spectroscopy (XPS) and photoemission electron microscopy (PEEM). We have developed a collinear type EXPEEM system using a Wien-filter-type electron energy analyzer. The collinear arrangement has the advantage of carrying out an easy alignment of the electron optical axis. We have measured EXPEEM images, mu-X-ray absorption near edge structure (mu-XANES) and mu-XPS of Au on Ta and Ag(DM)(2). We discuss the advantage of EXPEEM and future applications to organic devices.
