Carbon, Silicon and germanium atoms have 4 valence electrons each. Their valence and conduction bands are separated by energy band gaps represented by (EG)c,(EG)si and (EG)Ge, repectively. what is the relationship between above these things?

answered-by-expert Expert Answer
For carbon, Energy gap between conduction band and valance band is ˜ 5 eV ,
respective value for Silicon is 1.1 eV and for germenium it is 0.66 ev
 
Hence (EG)C > (EG)Si  > (EG)Ge
