Hubbard gap
WebMay 1, 1997 · A quasi-classical method for calculating the narrowing of the Hubbard gap between the A{sup 0} and A{sup +} acceptor bands in a hole semiconductor or the D{sup 0} and D{sup –} donor bands in an electron semiconductor is suggested. This narrowing gives rise to the phenomenon of a semiconductor transition from the insulator to metal state … WebMay 6, 2024 · Figure 1. Illustration of our mechanism for topological Hubbard band inversion. In the top panels, we start with a charge transfer insulator with 120° x y AFM order on the A (red) sublattice. The A quasiparticle band is split into a filled lower Hubbard band and an upper Hubbard band separated by energy U.The spin-degenerate B band lies in …
