Difference between valence and core electrons
WebJun 16, 2024 · The difference, shown in Figure 5, is not large, it is certainly much smaller than the values of the full profile shown in Figure 3; but one finds that the Hartree potential imbalance between one phase and the other shown in Figure 5 (0.33 eV) is clearly higher than the difference in results between both models (just 0.1 eV). Some other effects ...
