Leitungsbändern
Leitungsbändern, a German term roughly translating to "conduction bands," is a concept fundamental to understanding the electrical properties of solid materials, particularly semiconductors and conductors. In solid-state physics, electrons in atoms occupy discrete energy levels. When atoms come together to form a solid, these discrete levels broaden and merge into bands of allowed energy levels.
The conduction band is the lowest energy band that is partially or completely empty of electrons at
In insulators, the conduction band is separated from the highest filled band (the valence band) by a
Semiconductors exhibit intermediate behavior. They have a relatively small energy gap between the valence and conduction
