[1,2]. These directories are left empty as this data can be acquired from the associated data publications [3,4].&lt;/li&gt; &lt;li&gt;H&lt;sub&gt;2&lt;/sub&gt;O passivated slabs: The directories `passivation_H2O_full` contains AFLOW/VASP [5&amp;ndash;10] input and output files for structural relaxation and electronic band structure calculations.&lt;/li&gt; &lt;li&gt;Molecular dynamics simulations: The directories `MD_300K_PROB_0.01` contains VASP input and output files for molecular dynamics simulations at 300 K used to assess structural stability.&lt;/li&gt; &lt;/ol&gt; &lt;p&gt;Additional electronic analysis: For KSbO&lt;sub&gt;3&lt;/sub&gt;, an additional subdirectory `electronic_details` inside `passivation_H2O_full` contains charge density differences, local electrostatic potentials, and partial charge densities.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Solvation Calculations&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;For the 11 systems identified as dynamically stable, a duplicate of the directory tree described above is provided with the suffix `_water_solvation`. These directories contain VASPsol++ [11] solvation-corrected calculations for both pristine slabs and H&lt;sub&gt;2&lt;/sub&gt;O-passivated sheets.&lt;/p&gt;</dct:description>
