= Band diagram
{wiki=Band_diagram}
A band diagram is a graphical representation used in solid-state physics and semiconductor physics to illustrate the energy levels of electrons in a material. It shows the allowed and forbidden energy states in a solid, particularly highlighting the conduction band, valence band, and the bandgap. Here's a brief explanation of its key components: 1. **Valence Band**: This is the highest range of electron energy levels where electrons are normally present at absolute zero temperature.
