band gap

[/bænd ɡæp/]
nounpl: band gaps
largura da banda proibida
1. The energy difference between the valence band and the conduction band in a material, determining its electrical conductivity properties
The band gap of silicon is approximately 1.1 eV at room temperature.
A largura da banda proibida do silício é aproximadamente 1,1 eV à temperatura ambiente.
2. A range of energy levels in a material where no electron states exist, acting as a barrier to electron movement
Semiconductors have a moderate band gap, allowing electrons to be excited into the conduction band with moderate energy.
Os semicondutores possuem uma largura de banda proibida moderada, permitindo que elétrons sejam excitados à banda de condução com energia moderada.
This is a specialized term primarily used in physics, materials science, and semiconductor engineering. In Brazil, it is commonly taught in undergraduate physics and engineering courses. The term is often left untranslated in technical literature and research papers, even in Portuguese-speaking institutions, due to the international nature of scientific communication. Understanding band gap is fundamental to comprehending how semiconductors, insulators, and conductors function differently.
