👉 An electronic fluid, also known as an electron gas or a two-dimensional electron gas (2DEG), is a highly conductive, quasi-one-dimensional system of electrons that behaves like a fluid at the quantum level. Typically found in semiconductor heterostructures, such as those between GaAs and AlGaAs, these systems confine electrons to a plane, leading to unique electronic properties. In this context, the electrons move collectively rather than as individual particles, exhibiting collective behavior akin to a fluid. This collective motion results in phenomena like high electron mobility, quantum Hall effect, and the ability to manipulate electron transport with electric fields, making electronic fluids crucial in advanced electronics and quantum computing applications.
