A pure silicon crystal of length l(0.1m)...

A pure silicon crystal of length `l(0.1m)` and area `A(10^(-4) m^(2))` has the mobility of electron `(mu_(e))` and holes `(mu_(h))` as `0.135 m^(2)//Vs` and `0.48 m^(2)//Vs`, respectively, If the voltage applied across it is `2V` and the intrinsic charge concen-tration it is `2V` and the intrinsic charge concen-tration is `n_(i) = 1.5 xx 10^(6) m^(-3)`, then the total current flowing through the crystal is.

A

`8.78xx10^(-17)A`

B

`6.25xx10^(-17)A`

C

`7.89xx10^(-17)A`

D

`2.456xx10^(-17)A`

Text Solution

Verified by Experts

The correct Answer is:
A
`I=e(n_(e)mu_(e)+n_(h)mu_(h))(AV)/(l)`
Putting the values, we get
`I=8.78xx10^(-17)A`
