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.
