Magnetoexcitons in two-dimensional electronic systems

Physics-Uspekhi. 2015. Vol. 4. No. 58. P. 315-329.

Experimental and theoretical research on neutral
excitations in a two-dimensional electron gas in a strong mag-
netic field is reviewed. Methods for calculating excitation en-
ergies in the strong-field limit for integer and noninteger filling
factors are considered. The effects of impurities and of the
nonideality of the two-dimensional system on the excitation
spectrum are examined. Experimental results that have been
obtained by the method of inelastic light scattering and that lend
support to the current theoretical views are presented. We also
discuss possible avenues of future experimental and theoretical
work.
