Photoemission Electron Microscopy (PEEM) on Insulating Samples

Abstract

The observation method of photoemission electron microscopy (PEEM) on insulating samples has been established by introducing simple Au pattern evaporation equipment. Surface conductivity is induced locally on an insulating surface by continuous radiation of soft x-rays, and Au films close to the area of interest allow the accumulated charges to be released to a ground. Using this technique, all usersʼ experiments on poorly conducting samples have been performed successfully at the PEEM experimental station in SPring-8.
