This term refers to the energy difference between the top of the valence band and the bottom of the conduction band in a material.

Examples:

The band gap of silicon is around 1.1 eV.
Understanding the band gap is crucial for designing electronic devices.
The material's properties are determined by its band gap.

Alternatives:

energy gap
forbidden energy gap
energy band gap
semiconductor band gap
material band gap

This phrase is used when specifying that the band gap being discussed is measurable, meaning it can be quantified or observed.

Examples:

The material exhibits a measurable band gap of 2 eV.
Researchers were able to determine a measurable band gap in the semiconductor.
A measurable band gap is essential for the proper functioning of the device.

Alternatives:

a quantifiable band gap
a detectable band gap
an observable band gap
a measurable energy gap
a verifiable band gap

Both phrases are correct, but they are used in different contexts. "A measurable band gap" is used when referring to a band gap that can be measured, while "band gap" is a more general term that can be used without specifying if it is measurable or not.
