QUASI-PARTICLE RECOMBINATION AND SPATIAL ORDERING OF 2D ELECTRONS IN THE EXTREME QUANTUM LIMIT

Abstract:
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 ν = 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.
