Replication Data for: Space charge governs the kinetics of metal exsolution

The 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.
