(a) SEM image of a 10 µm gold lattice sample on an Si substrate. (b) Photoelectron intensity map at the Au 4f core level. A checkerboard pattern image with a 10 µm interval is obtained. (c) Survey spectra obtained at the center of a gold square and an Si substrate surrounded by gold squares. In the Si substrate region, the gold contribution is not detected. (d) AR-HAXPES spectra obtained at the Si substrate region. |
