Replication Data for: Space charge governs the kinetics of metal exsolutionhttps://doi.org/10.26165/JUELICH-DATA/CYHXRMWeber, MoritzŠmíd, BřetislavBreuer, UweRose, Marc-AndréMenzler, Norbert H.Dittmann, ReginaWaser, RainerGuillon, OlivierGunkel, FelixLenser, ChristianJülich DATA2023-11-152024-01-26T10:16:38ZThe present data repository contains all suitable data that provide the basis for the main figures of the manuscript as specified by the pulication guidelines. Accordingly, a record of text files are provided in the form of excel sheets for each relevant figure and named after the respective figure of the manuscript. Figure_1b.xlsx, Figure_2d_as-deposited_termination, Figure_2d_SrO_termination.xlsx, Figure_3d_STNNi-NbSTO.xlsx and Figure_3d_STNNi-NbSTO.xlsx contain experimental data on the properties of nanoparticles synthesized by metal exsolution as determined by evaluation of topological data obtained by atomic force microscopy. Figure_1c.xlsx contains experimental data on the cation depth profiles measured by secondary ion mass spectrometry. Figure_2a.xlsx contains XPS Ni 2p core-level spectra for different states of STNNi (different thermal oxidation / thermal reduction history and annealing time). Figure_2b.xlsx contains relative intenisty rations for the metal and oxide Ni 2p states as a function of the thermal oxidation / thermal reduction history and annealing time. Figure_2c.xlsx contains values of the space-charge induced binding energy shifts in the peak maxima of XPS O 1s, Ti 2p, Nb 3d and Sr 3d core-level recorded during consecutive thermal oxidation (p(O2) = 0.1 mbar, T = 400°C) and thermal reduction (p(H2) = 0.92 mbar, T = 400°C) steps relative to ultra high vacuum conditions. Figure_3b.xlsx and Figure_3c.xlsx contain data on the space charge potential profiles in the near-surface region of n-type STO obtained by finite-element electrostatic space charge simulations.ChemistryPhysicsMetal exsolution, Space charge, Oxide epitaxy, Nanostructured catalysts, Nanoparticles, Solid oxide cells10.1038/s41563-023-01743-6Weber, Moritz2023-10-05CC0CC0 Waiver
