The deposited files cover the Ag 3d, Hg 4f, Sn 3d, and S 2p core levels together with the valence-band region and include both numerical spectral data and corresponding graphical representations. The data can be used to examine the elemental composition, core-level electronic states, and valence electronic structure of the untreated Ag2HgSnS4 single-crystal surface. All deposited spectra correspond to the pristine surface.","keywords":["Chemistry","Engineering","Physics","Condensed matter physics","Surface science","Semiconductor","Semiconductors","X-ray photoelectron spectroscopy","Electronic structure","Ag2HgSnS4","Quaternary chalcogenide","Core-level spectra","Valence-band spectrum","Surface composition"],"citation":[{"@type":"CreativeWork","name":"Bozhko, V.V., Tretyak, A.P., Parasyuk, O.V., Ocheretova, V.A., and Khyzhun, O.Y.
