The intrinsic carrier density in germani...

The intrinsic carrier density in germanium crystal at 300 K is `2.5xx10^(13)` per `cm^(3)`. if the electron density in an N-type germanium crystal at 300 K be `0.5xx10^(17)` per `cm^(3)` the hole density (per `cm^(3)`) in this N-type crystal at 300 K would be expected around-

A

`2.5 xx 10^(13)//cm^(3)`.

B

`5 xx 10^(6)//cm^(3)`

C

`1.25 xx 10^(10)//cm^(3)`

D

`0.2 xx 10^(4)//cm^(3)`
