The Two-Dimensional Density of States at Fractional Filling Factors
Magnetocapacitance measurements have yielded the density of states of a two-dimensional electron gas from the weak-field limit to the extreme quantum limit. Quantitative information about the density of states...

Fractional Hall Quantization of Two-Dimensional Holes in Gaas-GaAlAs Heterostructures
The quantum Hall effect in two-dimensional electron systems has been reported in a number of heterostructures,1–4 in which the Hall resistance, ρxy =h/νe2, shows plateaus at integral values of ν and the magneto-r...
