Especially in condensed-matter physics, an energy gap is often known more abstractly as a spectral gap, a term which need not be specific to electrons or solids. Band gap [ edit]
WebA band gap is the distance between the valence band of electrons and the conduction band. Essentially, the band gap represents the minimum energy that is required to excite an electron up to a state in the conduction band where it can participate in conduction. [1] The lower energy level is the valence band, and thus if a gap exists between ... WebApr 11, 2024 · 1.Introduction. Metal oxide thin film transistors (MOTFTs) as next-generation electronics have been widely explored for their applications in flat panel display technology due to their excellent charge transfer properties and excellent optical transparency [1], [2], [3].As a MO material, In 2 O 3 is the best candidate for n-type TFTs.
