For the TiO2 bulk data set, structural energies were obtained from density-functional theory calculations using the PBE exchange–correlation functional1 as implemented in PWSCF of the Quantum ESPRESSO package.2 Wave functions and electron densities were represented in plane wave basis sets with energy cutoffs of 40 Ry and 200 Ry, respectively, using GBRV ultrasoft pseudopotentials for the atomic core regions.3 For the Brillouin zone integration, all calculations employed gamma-centered k-point meshes with a density corresponding to 8×8×8 k-points for the primitive rutile unit cell with 6 atoms. SCF energies were generally converged to 1.0 × 10−6 Ry and the convergence threshold for variable-cell optimizations was 0.5 kbar.
