There is a small energy gap between the conduction and valence bands of

Options

A. `E_(g)(T)=0.70-2.23xx10^(-4)TeV`
B. `E_(g)(T)=0.70+2.23xx10^(-4)TeV`
C. `E_(g)(T)=1.10-3.60xx10^(-4)TeV`
D. `E_(g)(T)=1.10+3.60xx10^(-4)TeV`

Answer

C

Explanation

For Si, `E_(g)(T)=1.10-3.60xx10^(-4)"TeV"`
For Ge, `E_(g)(T)=0.70-2.23xx10^(-4)"TeV"`
