Anomalous damping of low-frequency edge magnetoplasma oscillations in case of quantum Hall effect
Kosevich Yu. A.
The diffusion component of the current near a boundary gives rise to an additional damping of low-frequency edge magnetoplasma oscillations in inhomogeneous 2D electron systems (including superlattices). This damping increases with decreasing value of the dissipative conductivity σχχ. The possibility of experimentally observing the anomalous damping of edge magnetoplasma oscillations in the case of an integer quantization of the Hall effect is discussed.
