Formation energies of the impurities for interstitial and substitutional positions in hcp Ti lattice are calculated from “elemental” chemical potentials (μelement) and ‘oxide’ chemical potentials (μoxide), see Supporting information, that are listed in Tables 3 and 4, respectively. For example, Fig. 2a shows the … Zobacz więcej Titanium atoms occupying interstitial lattice sites are self-interstitials. In the hcp crystal lattice, a self-interstitial defect can be located at six sites in the unit cell as shown in Fig. … Zobacz więcej Chemical hybridization plays an important role for the configuration of impurity atoms in host lattices. An ideal measure of the orbital hybridization strength is the charge transfer between impurity and host atoms. The Bader … Zobacz więcej The formation energy of an atom missing from a lattice site, i.e., a vacancy (VTi, not to be confused with vanadium substituted on Ti site, VTi), is calculated as where E is the total energy … Zobacz więcej Witryna1 cze 2024 · An impurity atom exerts a strain on all the nearest neighbor (NN) host atoms and the magnitude of this strain depends directly on the impurity atom size. When there is a vacancy in the NN position of the impurity, it allows the large impurity atom to relax toward the vacancy, reducing the overall strain in the system.
