Potential and Charge Distribution at Semiconductor‐electrolyte Interfaces

The present article deals with the basic concepts of charge and potential distribution at semiconductor‐electrolyte interfaces. The authors use examples to show how external polarization and the variation of the electrolyte composition can change the potential drop across the space‐charge region in the semiconductor and in the Helmholtz double layer at the interface. The article also contains a detailed discussion of the effects exerted by surface properties and by injection of carries on the distribution of charge and potential.
