Examples of 'valence band' in a sentence
Meaning of "valence band"
Valence band: In physics and materials science, the valence band refers to a range of energy levels in a solid material that are occupied by valence electrons. It is important for understanding the electronic properties and behavior of materials, especially in the context of semiconductors and electrical conductivity
