Conductor and Semi in Material science – Study Material
The electrons in the outermost orbitals of the atoms, which constitute the solid, determine its electrical properties. The electron theory of solids aims to explain the structures and properties of solids through their electronic structure. The electron theory is applicable to all solids both metals & non – metals. It explains the electrical, thermal and magnetic properties of solids etc. For more details click the PDF link given below.

- Fermi – Dirac distribution function
- Fermi level
- Fermi Energy
- Intrinsic semiconductors
- Fermi Energy
- Extrinsic semiconductors
- Compound semiconductors
- Hall effect
Compound semiconductors :
Semiconductors formed by combinations of equal atomic fractions of fifth and third column or sixth and second column elements are called compound semiconductors.
Extrinsic semiconductors :
A semiconducting material in which the charge carriers originate from impurity atoms added to the material is called extrinsic semiconductor. The addition of impurity increases the carrier concentration and hence the conductivity of the conductor.
