Diode p-(GaMn)As/n-InGaAs/n+-GaAs heterostructures with different thicknesses (from 5 to 50 nm) of the (Ga,Mn)As dilute magnetic semiconductor layer have been fabricated and studied. The negative magnetoresistance effect reaching 6–8% is observed i

The influence of the random potential of Mn impurities in p-i-n resonant tunneling structures on the electronic spectrum has been studied. The possibility of the formation of zero-dimensional states in nanoelectrostatic quantum dots, as well as two-d

Giant fluctuations of the recombination-radiation intensity of two-dimensional electrons were studied in double quantum wells with different well and barrier widths in the regime of the integer quantum Hall effect. It was found that the giant fluctua

The spectra of magnetoplasma excitations in two-dimensional electron disks and rings are studied by optical detection of resonance microwave absorption. For ring-shaped structures, two types of edge magnetoplasma modes localized along the inner and o

The spectrum of excitonic excited states in GaAs/AlGaAs quantum wells of different width is studied together with its change due to the screening of electron-hole interaction by two-dimensional electrons. The exciton binding energy decreases sharply

We report microwave absorption studies on rings containing two-dimensional electrons. The absorption is measured on single rings with different widths using an optical luminescence technique. The dispersion of the plasmon modes has been determined in

Microwave absorption spectra of a single, narrow stripe of two-dimensional electrons have been recorded with an optical detection scheme in order to investigate the dispersion of one-dimensional (1D) plasmons. For narrow stripes the dispersion of 1D
