Abstract

The spectra of edge magnetoplasma excitations in two-dimensional (2D)
electron disks have been analyzed by the method of optical detection of
resonant microwave absorption. The magnetic dispersion of an edge
magnetoplasmon in samples with a high 2D electron density is found to
be poorly reproduced by existing theoretical models. Analysis of the
magnetic-field dependence of the linewidth of resonant microwave
absorption for samples with various 2D electron densities shows that
the inverse width of the main mode of resonant microwave absorption is
universally proportional to the Hall resistance of 2D electrons.
