the promotion becomes energetically feasible and one or even two electrons are always promoted to the 4s subshell. (Similar promotions happen for every transition metal atom but one, palladium.)[13] Chromium is the first element in the 3d series where the 3d electrons start to sink into the ...
atom from the PE sites leads top–dcoupling decreasing the total energy, which is confirmed by the calculated electronic structure of Cu(CrBr3)2as followed. Figure1cshows the projected density of states (PDOS) of the Brporbital and Cudorbital in the paraelectric and ferroelectric phases, ...
Moreover, Cr-C orbital hybridization tends to be stronger due to the decreased partial density of states (PDOS) of the Cr atom. The difference in electronic distribution of binary carbides has also been investigated, which confirmed that overall orbital hybridization and covalent characteristics has...
