energy gap
noun
- physics the difference of energy between the bottom of the conduction band and the top of the valence band of the electrons in a crystalline solid. For values below about 2eV the substance is considered to be a semiconductor whilst for higher values it is considered to be an insulator
Example Sentences
Instead of heeding a memo from one of his pollsters urging him to focus on lowering the demand for oil, he put most of his effort into trying to make up the post–oil shock energy gap.
"This allowed us to measure an unexpected energy gap -- the hallmark of an insulator."
The authors' suspicion that the experimentally measured energy gap was a signature of a Mott insulating phase was confirmed by comparing experimental results with dynamical mean-field theory calculations.
The authors were able to observe this metallic phase from a vanishing of the measured energy gap when they removed some electrons from the MOF.
But even assuming the signal is from Majoranas, the tiny energy gap Microsoft reported would offer limited protection in real world operations, says Mike Zaletel, a theorist at UC Berkeley who previously worked on the nanowires at Station Q. “It’s hard to see that they would have a very robust qubit with a gap that small.”
