Abstract

We have studied the magnetoresistivity ρ{variant}xx and Hall resistivity ρ{variant}xy in GaAs/AlxGa1-xAs heterostructures at low temperatures. The half-width Δν(T) of ρ{variant}xx peaks exhibits the power-law dependence Δν∼Tκ{script} with the exponent κ{script} = 0.50 ± 0.03. This result has been explained by the model which accounts for the scaling behavior in terms of variable range hopping.
