Which of the following equations correct...

Which of the following equations correctly represents the temperature variation of energy gap between the conduction and valence bands for Si?

A

`E_g(T)=0.70-2.23xx10^(-4)` T eV

B

`E_g(T)=0.70+2.23xx10^(-4)` T eV

C

`E_g(T)=1.10-3.60xx10^(-4)` T eV

D

`E_g(T)=1.10+3.60xx10^(-4)` T eV

Text Solution

Verified by Experts

The correct Answer is:
C
The energy gap `E_g` depends on the temperature .
For silicon ,`E_g(T)=1.10-3.60xx10^(-4)` T eV
For germanium , `E_g(T)=0.70-2.23xx10^(-4)` TeV
