摘要：

The ac impedance theory at a semiconductor-liquid junction indicates that the addition of redox couples to an electrolyte solution makes it possible to determine properties of the surface states from capacitance and conductance measurements. In particular, the surface-state capacitance disappears when the electron exchange between the surface states and redox couples is dominant compared with the electron exchange between the surface states and the conduction band.
