Q. The relation between the energy $E_{f}$ of fermi level, height $E_{b}$ of potential barrier and work function $W_{0}$ is
A) $E_{f} = W_{0} + E_{b}$
B) $E_{b} = W_{0} - E_{f}$
C) $E_{b} = W_{0} + E_{f}$
D) $W_{0} = E_{b} + E_{f}$
Explanation
(c) Potential barrier energy $\left( E_{b} \right) =$work function $\left( W_{0} \right) +$fermi energy $(E_{f})$.
