Photoluminescence in the Fractional Quantum Hall Effect

摘要: The fractional quantum Hall effect results from a correlated ground state of interacting electrons confined to layer and subject strong transverse magnetic field. It exhibits dissipationaless conduction ρxx = 0 quantization the resistance RH hv/e , with v-the Landau level filling number-a rational fraction. This paper will address magneto-optics states. For ideal system coplanar holes photoluminescence (PL) spectrum occurs at isolated magnetoexciton binding energy, independent underlying electron density therefore does not reflect any features associated effect. If, however, hole layers are far enough apart PL coincides single particle spectral (tunneling) states ρ(ω). primary fillings v 1/m, ρ(ω) characteristic peak. In presence quasi-particle excitations develops an additional peak intensity proportional number quasi-particles shifted in energy main by quasi-hole gap.
