👉 Bandgap is a concept in physics that refers to the difference between the conduction band of an atom and the valence band. The band gap is a measure of how much energy it takes for an electron to travel from one sub-level (valence) of an atom to another (conduction). It is a fundamental property of most semiconductors, which are materials that can conduct electricity but not as well as insulators. In general, the higher the band gap, the more heavily
