Abstract

Photoelectron diffraction is an effective method to analyze element-specific atomic structures of surfaces. Recently, the Two-dimensional photoelectron spectroscopy (2D-PES) end station at the soft x-ray beamline BL25SU, SPring-8 was upgraded. Few-10-μm diameter focused beam is now available for measuring poly-crystalline and small crystalline samples. We show a series of photoelectron diffraction patterns from gold poly-crystalline surfaces mapped in two dimensions at an interval of 20μm. The sample surface position was two-dimensionally scanned and the best crystalline quality position was searched for the measurements of full-hemisphere photoelectron diffraction patterns and spectra.
