摘要：

The inter-band photoluminescence spectrum of an incompressible liquid at an ultra-high mobility GaAs heterojunction may show multiple recombination channels in which different integral numbers of fractionally charged excitations participate. The spectrum at nu = 1/2 is discussed in terms of the proposed composite fermion model of the fractional quantum Hall effect. Changes in the photoluminescence spectrum at higher field lead to the proposal of an experimental test for magnetic-field-induced crystalline order.
