Definitions for "Valence band"
Highest filled or almost filled band in a semiconductor
The highest energy band in a solid that contains electrons.
The energy level which contains molecularly bound electrons which can not move within the crystal lattice. For there to be conduction in a semi-conductor, valence electrons much be stimulated to overcome the energy gap and enter the conductance band.
