We find an overall decrease in the anharmonicity while increasing the pressure. Using some specific interatomic potential functions, we are able to corroborate the analytical resultsengAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Anharmonic crystalPressure effectSurface thermodynamicArtigo10.1016/j.physa.2021.126115
