- Please,please help me The manifestation of band structure in solids is due to
The manifestation of band structure in solids is due to
- Option 1)
Heisenberg’s uncertainty principle
- Option 2)
Pauli’s exclusion principle
- Option 3)
Bohr’s correspondence principle
- Option 4)
Boltzmann’s law
Answers (1)
As we learnt in
Semiconductor -
Energy gap between valence band and conduction band is less than 3 e.v.
- wherein
1) lies between conductor & insulator
2) Both electron and holes are responsible for conductivity .
3) At 0 K behave like an insulator (Si,Ge)
It is due to pauli's exclusion principle: no two electron can have same set of all four quantum number. Hence electron's occupies gradually higher energy level.
Correct option is 2.
Option 1)
Heisenberg’s uncertainty principle
This is an incorrect option.
Option 2)
Pauli’s exclusion principle
This is the correct option.
Option 3)
Bohr’s correspondence principle
This is an incorrect option.
Option 4)
