Question

Carbon, silicon and germanium have four valence electrons each. These are characterised by valence and conduction bands separated by energy band gap respectively equal to $(E_{g})_{C}, (E_{g})_{S i}$ and $(E_{g})_{G e}$ .Which of the following statements is true?

A

$(E_{g})_{S i} < (E_{g})_{G e} < (E_{g})_{C}$

B

$(E_{g})_{C} < (E_{g})_{G e} > (E_{g})_{S i}$

C

$(E_{g})_{C} > (E_{g})_{S i} > (E_{g})_{G e}$

D

$(E_{g})_{C} = (E_{g})_{S i} = (E_{g})_{G e}$
