The band gaps of a conductor, semiconductor and insulator are respectively `Eg_(1), and Eg_(2) and Eg_(3)`. The relationship between them can be given as ………

A

`E_(g1) gt E_(g2) lt E_(g3)`

B

`E_(g1) gt E_(g2) gt E_(g3)`

C

`E_(g1) glt E_(g2) gt E_(g3)`

D

`E_(g1) lt E_(g2) lt E_(g3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Band gap of Insulator is highest, while that of conductor is least. So,
`E_(g1) gt E_(g3) gt E_(g2)`
`E_(g1) gt E_(g2) `
`E_(g3) gt E_(g2)`
`E_(g1) gt E_(g2) lt E_(g3)`
