bandgap
This term is a specialized technical expression used primarily in solid-state physics and materials science. It describes a forbidden energy range where no electron states can exist, acting as a threshold that determines whether a material behaves as a conductor, semiconductor, or insulator.
In professional discourse, the term is often used as a modifier in compound phrases such as "bandgap engineering," referring to the process of controlling or altering the energy gap to create specific electronic properties in a device. It is almost exclusively used in scientific and engineering registers and is rarely encountered in general conversation.
Meanings
Examples
The material has a wide bandgap that makes it suitable for high voltage applications.
We need to calculate the direct bandgap of this semiconductor to determine its optical properties.
Does this crystal have a narrow bandgap or a wide one?
The photon energy must be greater than the bandgap to excite an electron.
I wonder if adjusting the alloy composition will shift the bandgap.
Silicon is widely used because its bandgap allows for efficient transistor operation at room temperature.
