For the six Nb/Al2O3(1120) coherent structures, we focused on the difference of Mulliken population of oxygen atoms (∆m(O)) that are near the interface, as all of them have the same substrate (O-terminated Al2O3(1120)). Here, ∆m(O) = m − m′, m and m′ is the ...
electronegativity actually varies depending on an atom's environment. However, most of the time an atom displays similar behavior in different situations. Factors that affect electronegativity include the nuclear charge and the number and location of electrons in ...
