The manifestation of band structure in solids is due to

  • Option 1)

    Heisenberg’s uncertainty principle

  • Option 4)

    Boltzmann’s law

As we have learnt,

 

Semiconductor -

Energy gap between valence band and conduction band is less than 3 e.v.

- wherein

1) \Delta E_^{g} lies between conductor & insulator 

2) Both electron and holes are responsible for conductivity .

3)    At 0 K behave like an insulator (Si,Ge)

 

 Due to Pauli exclusion principle, no two electron can have same set of all four quantum number.

Hence electrons have different energy level, which is the reason for band structure in solid.
