two-dimensional electron gas

[‚tü di′men·shən·əl i¦lek‚trän ′gas]
(solid-state physics)
A system of electrons that are confined by opposing forces to a thin planar region adjacent to an interface or within a thin layer of material, but are free to move along the plane scattering off each other.

Objective: Under high magnetic field and at low temperatures, Electronic interactions in a two-dimensional electron gas give rise to exotic, Strongly correlated many-body quantum hall states.
In a reciprocal approach, we will exploit the many-body nature of optical excitations in a two-dimensional electron gas to enhance polariton-polariton interactions.
