The electric double layer (EDL) refers to a structure that forms at the interface between a conductive material (like a metal or a semiconductor) and an electrolyte. This structure consists of two layers of charge: one formed by ions adsorbed on the surface of the conductive material and the other by counter-ions in the electrolyte. This phenomenon is crucial in understanding the behavior of nanoscale devices, particularly in fields like nanofluidics and nanoelectronics.
