From the perspective of sp orbital hybrid bonding and its consequence on the behavior of valence electrons, new insight is presented into the nature of oxygen-derived features in the valence band and above of metals. It is suggested that the crystal geometry and the surface morphology may vary ...
(PAW)51method and a plane-wave cutoff of 500 eV was used for the valence electrons. Van der Waals interactions were considered via dispersion-corrected density functional theory calculation (DFT-D3)52in the simulations. The Gaussian smearing method with a smearing width of 0.05 eV was ...
Bader charge analysis has been conducted to check the valence electrons on W and O atoms.References Demasius, K. U. et al. Enhanced spin–orbit torques by oxygen incorporation in tungsten films. Nat. Comm. 7, 10644 (2016). Article ADS CAS Google Scholar Pai, C. F. et al. Spin ...
the calculation results showed that the introduction of S vacancies could narrow down the bandgap between the top and bottom valence bans, which indicated the possible enhancement of the electronic conductivity of SnS2(Fig. 10i-k). Consequently, the hierarchical SnS2microspheres electrode has a supe...

The Auger electron spectra (AES) and electron energy loss spectra (ELS) of a clean and hydrogen, oxygen, sulphur covered titanium sample were recorded with a cylindrical miror analyzer. Information on the valence electrons density of states is derived from the shape of the M 2,3VV Auger ...
(i.e., the average energy of the band) was generally adopted. Upon adsorption on the TM surface, the valence states of the adsorbate couple with the TMsstates and become broadened and shift downward, which then continue to interplay with the TMdstates and form the filled bonding states and...
SummaryPerovskite electrocatalysts strongly rely on electronic structure regulation, especially for electron configuration (eg) and conductivity. However, current regulation strategies inevitably involve ambiguous entanglement of crystals, electrons, and spin degrees of freedom. Here, we developed a spin-state...
For IrO2the valency of the transition-metal ionMis close to the nominal valence of +IV inMO2(ref. 26). EachVOgenerates two defect electrons due to charge neutrality. To minimize Coulomb interaction, the defect electrons will tend to localize at differentMions in the vicinity of theVO. In...
