The energy band gap is maximum in

  • Option 1)

    metals

  • Option 2)

    superconductors

  • Option 3)

    insulators

  • Option 4)

    semiconductors.

 

Answers (1)

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)

 

 energy band gap order 

super conductor < conductor < semiconductor < Insulator

 

 


Option 1)

metals

Option 2)

superconductors

Option 3)

insulators

Option 4)

semiconductors.
