Measurements of the Hall and Shubnikov-de Haas effects of a 2-dimensional electron gas in an Al x Ga1-x As/GaAs heterojunction interface have been performed. The electron density and mobility decayed together when the gate voltage was applied. The data of the Hall voltage and the source-drain current as functions of the gate voltage are transformed to magnetoconductances σ x x and σ x y , using Wick's theory to clarify the quantization of the conductance at the Landau level tails.
