摘要：
The nonlinear collective excitations of a two-dimensional electron gas (2DEG) formed at the interface of a heterostructure are presented. A matrix formulation of the coupled particle dynamics-electromagnetic field equations permits the extraction of the equation of evolution for these excitations. The stationary solutions of the equation are presented. A new class of solitary excitations is shown to form part of the nonlinear mode spectrum of excitations of the 2DEG in the low wave-vector plasmon-polariton regime.
