The electronic structure and surface chemical states of a Cu2HgGeSe4 single crystal, grown by the Bridgman–Stockbarger method, were investigated using X-ray photoelectron spectroscopy (XPS) for pristine and Ar+ ion-irradiated surfaces. High-resolution core-level XPS spectra (Cu 2p, Hg 4f, Ge 3d, Se...
