Carbon, silicon and germanium have four
valence electrons each. These are characterized
by valence and conduction bands separated by
energy band gap respectively equal to (E)
(E)si and (E)Ge Which of the following
statements is true ?
(a) (E)c = (E) = (E)Ge
(b) (E) > (E) > (E)Ge
(c) (E) <(E)Ge>(E)s
(d) (E)si <(Eg)e > (Eg)c
