WebTypically, a modified Fang-Howard wave-function is used to model the penetration in to the ternary alloy barrier. The more the wave-function penetration or more disordered the alloy is, the lower would be the carrier mobility. However in the present structure under zero bias, we can safely assume the FL Mo x W 1-x S 2 Webwave functions is therefore not entirely unphysical. The problem is that the amount of Landau level mixing in a given composite fermion wave function is fixed, whereas in real experiments it depends on the parameter λ. Recently Manoharan et al. [5] have measured the fractional QHE energy gaps in high
