摘要：
A microwave cavity perturbation cryostat was constructed for the measurement of the quantum Hall effect. The conductivity and the dielectricity on the two-dimensional electron system have been measured at low temperature. Rapid changes in the resonant frequency shift and the resonance width were observed with increasing the magnetic field. These changes reflect the dielectric properties of the sample accompanied by the rapid decrease of the conductivity. In higher magnetic field, we observed oscillations of the cavity parameters in accordance with the quantum Hall effect. (C) 2003 Elsevier Ltd. All rights reserved.
