While band insulators are usually described in wavevector space in terms of fully filled bands, they are sometimes also described in terms of a complementary Wannier picture in which electrons occupy localized, atom-like orbitals. Under what conditions does the latter picture break down? The presenc...
Since Laves phases are predominantly metallic in bonding nature and largely governed by geometric space-filling principles, the metallic atom radii R of the atoms forming the compound have often been used to evaluate atomic size factors involved in the occurrence of these phases. An atom with a ...
The orbitals and their properties, obtained from Desclaux's 1973 Fock–Dirac neutral atom calculations for Z=1–118, are employed to verify our analysis. 2002 Wiley Periodicals, Inc. Int J Quantum Chem, 2002doi:10.1002/qua.965Leland C. Allen...

Theoretical calculations show that a narrow bandgap is obtained due to the induced intermediate band derived from the combination of the porbitals of Bi atoms and structure reconstruction, which promotes the electrocatalytical performance. This research introduces a new strategy to design channel ...
A molecular orbital analysis reveals that the transition state is stabilized by two filled 3d orbitals that mix with the HOMO and LUMO of methane respectively, indicating how the energy and occupation of the 3d orbitals determine the reaction barrier. The studies offer a strategy for identifying ...
