Definitions for "Double layer"
(electric) is the juxtaposition of an electric sheath containing an excess of electrons upon an electric sheath which is electron-deficient. Such a double layer is formed whenever two plasmas of differing electric charge densities meet, for example, between the Sun's photosphere and its corona and between the solar wind and the Earth's plasmasphere. The former double layer forms the solar chromosphere, the latter the Earth's magnetosphere and bow wave.

PCB Laminate with two layers of conductors forming a circuit pattern.
The interface between an electrode or a suspended particle and an electrolyte created by charge-charge interaction (charge separation) leading to an alignment of oppositely charged ions at the surface of the electrode or particle. The simplest model is represented by a parallel plate condenser of 2 x 10 cm in thickness. In general the electrode will be positively charged with respect to the solution..
