Analysis of Ag2HgSnS4 Compound by X-ray photoelectron spectroscopyhttps://doi.org/10.48788/DVUA/U6JWSRTkach, ViraO.Y. KhyzhunN.M. DenysіukKopylova Kateryna IhorivnaDataverseUA2026-08-242026-08-24T10:49:54ZThis dataset contains survey, high-resolution core-level, and valence-band X-ray photoelectron spectroscopy (XPS) data obtained from the pristine surface of an Ag2HgSnS4 single crystal grown by the Bridgman–Stockbarger technique. 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.ChemistryEngineeringPhysicsSemiconductorsX-ray photoelectron spectroscopyElectronic structureAg2HgSnS4Quaternary chalcogenideCore-level spectraValence-band spectrumSurface compositionEnglishBozhko, V.V., Tretyak, A.P., Parasyuk, O.V., Ocheretova, V.A., and Khyzhun, O.Y.
