Carbon, silicon and germanium atoms have four valence electrons each. Their valence and conduction bands are separated by energy band gaps represented by (Eg)C, (Eg)si and (Eg)Ge respectively. Which one of the following relationships is true in their case?
(Eg)C > (Eg)Si
(Eg)C < (Eg)Si
(Eg)C = (Eg)Si
(Eg)C < (Eg)Ge.
Band gap of carbon is 5.5 eV while that of
silicon is 1.1 eV
$$ \therefore $$ (Eg)C $$>$$ (Eg)Si
