Abstract
Experimental data are reported on studying cyclotron resonance
in a two-dimensional electron system with an artificial random
scattering potential generated by an array of self-organized
AlInAs quantum islands formed in the plane of an AlGaAs/GaAs
heterojunction. A sharp narrowing of the cyclotron resonance
line is observed as the magnetic field increases, which is
explained by the specific features of carrier scattering in
this potential. The results obtained point to the formation of
a strongly correlated electron state in strong magnetic fields
at carrier concentrations smaller than the concentration of
antidots. (C) 2001 MAIK "Nauka/ Interperiodica".
