In $P$-type semiconductors,the majority and minority charge carriers are respectively:

If $N_h$ and $N_e$ are the numbers of holes and conduction electrons in an extrinsic semiconductor,respectively,then:

When an $n$-type semiconductor is heated,

In a $p$-type semiconductor,which of the following statements is true?

Assertion: The number of electrons in a $p-$type silicon semiconductor is less than the number of electrons in a pure silicon semiconductor at room temperature.
Reason: It is due to the law of mass action.

In a $P$-type semiconductor,the acceptor energy levels $E_A$ are located:
