Quantum magnetotransport in the double-quantum-well hole system inside a wide Ge1-xSix/Ge/Ge1-xSix potential well

It is established from the Hall quantum effect measurements that occupied states of the quasi-two-dimensional hollow gas with the density of ps (3-5)x1015 m-2 are generalized for the whole Ge-layer by its thickness of dW < ∼ 25 nm, however, by the ps ∼ 5 x 1015 m-2, dW > ∼ 35 nm there takes place the hollow gas division into two-equivalent two-dimensional sublayers, concentrated near the well walls. The recently revealed open electron phase of the Hall dielectric is determined in the intermediate case of weakly-bound layers
