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 ) Si and (E g ) Ge . Which of the following statements is true?

Options

  1. A(E g ) Si g ) Ge g ) C
  2. B(E g ) C g ) Ge > (E g ) Si
  3. C(E g ) C > (E g ) Si > (E g ) Ge
  4. D(E g ) C = (E g ) Si = (E g ) Ge

Correct answer

C. (E g ) C > (E g ) Si > (E g ) Ge

Step-by-step solution

Correct Option is : (C) (E g ) C > (E g ) Si > (E g ) Ge
