Single crystal growth and the electronic structure of TlPb₂Br₅https://doi.org/10.48788/DVUA/EHLZITTkach, ViraO.Y. KhyzhunN.M. DenysіukLuzhnyi Ivan VasyliovychKopylova Kateryna IhorivnaDataverseUA2026-08-242026-08-25T09:31:55ZThis dataset contains survey, high-resolution core-level, and valence-band X-ray photoelectron spectroscopy (XPS) data obtained from the pristine surface of a TlPb2Br5 single crystal grown by the Bridgman–Stockbarger technique. The deposited files cover the Tl-4f, Pb-4f, and Br-3d 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 TlPb2Br5 single-crystal surface. All deposited spectra correspond to the pristine surface.ChemistryEngineeringPhysicsSemiconductorsX-ray photoelectron spectroscopyElectronic structureQuaternary chalcogenideCore-level spectraEnglishKhyzhun, O.Y., Bekenev, V.L., Parasyuk, O.V., Myronchuk, G.L., and Kityk, I.V.
