中文摘要	the transient charge response q(t) of a two-dimensional electron gas (2deg) in gaas/alxga1-xas heterostructures to a small pulse of the gate voltage, applied between the top gate and source electrodes in a corbino structure, was employed to directly measure the effective diffusion constant of a 2deg in the quantum hall regime. the measured diffusion constant d showed a drastic change as the magnetic field was swept through the integer fillings of the landau levels.
