The energy gaps `(E_(g))` between valence band and conduction band for diamond, silicon and germanium are in the order

A

`E_g "(diamond) gt " E_(g) "(silicon) gt " E_g "(germanium)"`

B

`E_g "(diamond) lt " E_(g) "(silicon) lt " E_g "(germanium)"`

C

`E_g "(diamond) = " E_(g) "(silicon) = " E_g "(germanium)"`

D

`E_g "(diamond) gt " E_(g) "(germanium) gt " E_g "(silicon)"`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) is correct option because diamond is an insulator and non-metallic character decreases down the group.

Let (Delta)E denote the energy gap between the valence band and the conduction band.The population of conduction electrons (and of the holes)is roughly proportional to e^(-Delta E//2kT). Find the ratio of the concentration of conduction electrons in diamond to that in silicon at room tempareture 300K. (Delta E) for silicon is 1.1 ev and for diamond is 6.0eV.How many conduction electrons are likely to be in one cubic meter of diamond ?
