Conduction of electricity in semiconductors

Click For Summary
SUMMARY

The discussion focuses on the conduction of electricity in semiconductors, specifically detailing the valence band and conduction band. The conduction band represents the energy range necessary for electrons to move freely, while the valence band contains electrons bound to their atoms. The energy gap between these two bands is crucial in classifying materials as conductors, insulators, or semiconductors. For further understanding, Hyperphysics provides an informative resource on the band theory of solids.

When studying about semiconductos what are the valence band and conductivity band .what are its properties,where is it addressed.
 
Physics news on Phys.org
It's all in the names! The conduction band is the range of energies required to free an electron from its atom, letting it move freely through the lattice, therefore conducting electricity. The valence band is then the highest range of energies of electrons which are bound to the atom. The energy gap between the valence band and the conduction band determines whether a material is a conductor, insulator or semiconductor.

Hyperphysics has rather a good writeup on the band theory of solids. http://hyperphysics.phy-astr.gsu.edu/hbase/solids/band.html
