forbidden energy gap or energy gap or band gap or band or Eg is the gap between the top of the valance band and bottom of the conduction band. If we apply the energy equivalent to Eg then the electrons in valance band will jump to the conduction band.

What is difference between semiconductor and superconductor?

A semiconductor only allows some electrons to flow across its junction. It has some resistance, in fact more resistance than a conductor but less than an insulator. A superconductor has no resistance.


What is the difference between solid state laser and semiconductor laser?

LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.


What is the difference between the energy gap of a semiconductor and a superconductor?

Energy gap in a superconductor is not a constant but depends on temperature. Energy gap in a semiconductor is a fixed quantity which does not depend on temperature. The excited quasiparticles or cooper pairs are produced two at a time hence the gap is 2Delta0. In a semiconductor the gap is the energy needed to excite 1 electron into the conduction band. The ground state in a superconductor is made of superconducting cooper pairs , above the gap the electrons are unpaired , the cooper pairs have lower energy. Conduction takes place in the lower ground state in Superconductors , where in semiconductors the electrons conduct from the conduction band. In a superconductor the gap is tied to the fermi level , while in a semiconductor it is fixed to the lattice in reciprocal space.
