Table 3. Comparison of DFT Calculations Performed on Our 76 Material Candidates by Structural Typea.
| type | no. candidates | |δbonds| (%) | |ΔEf| (eV/atom) | |δcell| (%) |
|---|---|---|---|---|
| perovskites | 30 | 5.23 | 0.57 | 0 |
| Heusler | 22 | 1.44 | 3.34 | 0 |
| binaries | 24 | 10.88 | 2.65 | 0 |
The geometry-optimized DFT results were compared against their cognate VAE-generated crystal structures. Results are analyzed in terms of difference in the absolute in formation energy, |ΔEf|, mean absolute percentage change in bond lengths, |Δbonds|, and unit-cell parameters, |Δcell|.
