Double layers were described in 1929 by the plasma pioneer and Nobel laureate Irving Langmuir. They form when electric current flows through plasma. Another Nobel laureate, Hannes Alfvén, described a double layer as, “… a plasma formation by which a plasma — in the physical meaning of this word — protects itself from the environment. It is analogous to a cell wall by which a plasma—in the biological meaning of this word—protects itself from the environment.”
