Question

Define Fermi energy in -
1) Conductor 2) Semiconductors plz help

Answer 1

Conductor

Conductors are generally substances which have the property to pass different types of energy. In the following, the conductivity of electricity is the value of interest.

Semiconductors

Semiconductors are solids whose conductivity lies between the conductivity of conductors and insulators. Due to exchange of electrons - to achieve the noble gas configuration - semiconductors arrange as lattice structure. Unlike metals, the conductivity increases with increasing temperature.

Increasing temperatures leads to broken bonds and free electrons are generated. At the location at which the electron was placed, a so-called defect electron ("hole") remains.

Answer 2

1. Conductors are metals.They do not have forbidden energy gap.So for conductors Fermi energy is 0.
2. For Semiconductors there is some forbidden gap and there fermi energy is less than 3eV.
I hope it will help u...
