Question

Band gap of silicon is E$_g$ (Si) of germanium is E$_g$ (Ge) and of carbon is E$_g$ (C). The correct order of band gap is

• 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. $E_g(Si) > E_g (Ge) > E_g(C)$

Answer 1

Answer: (B)

$E_g(Si)> E_g(Ge) < E_g(C)$

Answer 2

Answer (b) $E_g(Si)> E_g(Ge) < E_g(C)$
