A) \[{{E}_{g}}(Si)<{{E}_{g}}(Ge)<{{E}_{g}}(C)\]
B) \[{{E}_{g}}(Si)>{{E}_{g}}(Ge)<{{E}_{g}}(C)\]
C) \[{{E}_{g}}(Si)<{{E}_{g}}(Ge)>{{E}_{g}}(C)\]
D) \[{{E}_{g}}(Si)>{{E}_{g}}(Ge)>{{E}_{g}}(C)\]
Correct Answer: B
Solution :
Band gap of silicon is 1.11 eV, of germanium is 0.67 eV and so the correct order of band gap is \[{{E}_{g}}\,(Si)>{{E}_{g}}(Ge)<{{E}_{g}}(C)\].You need to login to perform this action.
