Structure of the Interface -IHP -OHP -Diffuse layer

Charge and Potential Distribution at the Interface Now you have a charge distribution at the interface. Then what happens at the interface? OK. Now you replace a metal electrode with a semiconductor. Then, how would the charge distribution change? Now the charges will be distributed in 1) 2) 3)
