Webb7 sep. 2024 · Semiconductors are classified by the fully occupied valence band and unoccupied conduction band. With the small band gap in between these two bands, it takes a certain amount of energy to excite the electrons from the valence to conduction band. Thus it follows that the higher the temperature, the more conductive the solid will be ( … Webb1 dec. 2003 · The origin of a “flat band” as defined in the “flat band–steep band” model for superconductivity has been studied. A “local inversion center” is derived mathematically as the necessary and sufficient condition for an occurrence of a “flat band” at an arbitrary k → point. From the k →-dependent part of E(k → j), a “pseudo-inversion center” is …
