DFT structure optimisations and DFT-based AIMD simulations were performed using the QUICK-STEP part of the CP2K code, installed on the HLRN-III/HLRN-IV facilities of the North-German Supercomputing Alliance. All calculations employed the PBE exchange-correlation functional in conjunction with Grimme's D3 dispersion correction. This PBE-D3 functional delivered fairly accurate results in a recent benchmarking study of zeolites and zeotypes, and it was successfully used in previous AIMD investigations of fluoride-containing zeolites. A plane-wave energy cutoff of 600 Ry was used, and the first Brillouin zone was sampled at the Γ point, only, in keeping with previous work. The calculations employed Goedeker-Teter-Hutter pseudopotentials devised by Krack. Gaussian triple-zeta (TZVP/TZVP-SR) basis sets were used in the structure optimisations, whereas the AIMD simulations used double-zeta (DZVP-SR) basis sets. These basis sets are available in the BASIS_MOLOPT_UCL (TZVP-SR basis sets for Al, Ga, Ge) and BA-SIS_MOLOPT (all others) files distributed with the CP2K code.
