Lets `n_p`and `n_e` be the number of holes and conduction electrons in an intrinsic semiconductor.

Lets n_p and n_e be the number of holes and conduction electrons in an extrinsic semiconductor.

n-type semiconductor is

How may the conductivity of an intrinsic semiconductor be increased ?

How the no. of electron and no. of holes are related in intrinsic conductor ?

What are n-type semiconductors ?

The probability of electrons to be found in the conduction band of an intrinsic semiconductor at a finite temperature

Assertion: The probability of electrons to be found in the conduction band of an intrinsic semiconductor at a finite temperature decrease exponentially with increasing band gap. Reason: It will be more difficult for the electron to cross over the large band gap while going from valence band to conduction band.

A N - type semiconductor is

Assertion: The conductivity of an intrinsic semiconductor depends on its temperature. Reason The conductivity of an intrinsic semiconductor is slightly higher than that of a lightly doped p-type semiconductor.

We have valence electrons and conduction electrons in a semiconductor. Do we also have "valence holes" and "conduction holes"?
