The description of structure and bonding in solids given in the preceding sections is largely qualitative, but it is a fair (although abbreviated) account of most of what was generally known as a result of quantum mechanical analysis in the period from 1930 to 1960. Starting in 1960 a more ...
By comparison, more delocalized ionic bonding takes place between Fe3+ and Ge/Te ions. This difference between localized and delocalized electron distributions around the Fe3+ and Fe2+ ions is also supported by deformation charge density analysis and Bader charge (see Supplementary Fig. 2 and ...
To explain the different dependences of carrier mobility on carrier concentration, the polar coupling constants of the half-Heusler compounds are calculated using the Eq. (1) (see Supplementary Table 1 and Supplementary Fig. 7 for details). A comparison of the polar coupling constants between ...
The electrons are localized between Fe2+ and Ge/Te ions, indicating covalent bonding characteristics. By comparison, more deloca- lized ionic bonding takes place between Fe3+ and Ge/Te ions. This difference between localized and delocalized electron 2 COMMUNICATIONS PHYSICS | (2022)5:140 | https...
