electrical double layer

https://doi.org/10.1351/goldbook.14008
Array of charged species and oriented dipoles existing at a solid-solution interface. The solid may be a metal or a semiconductor. Double refers to the fact that the surface charge and its counter charge at the solution side are included.
Note: Often the solution side is considered to be composed of a thin inner layer of (hydrated) ions in contact with the surface and a diffuse layer further out in solution.
