摘要：

The structures containing networks of one dimensional quantum wires were obtained through the self-formation at electrochemical etching of multilayer low-dimensional InGaAs/GaAs structures with quantum wells. We report and discuss this fact for the first time. A decrease in the dimensionality of electron-hole gas in the objects of interest, which is due to a 2D to 1D electron subsystem transformation in the layers of this structure, was demonstrated by the shift and narrowing of resonance lines in the photoluminescence spectrum.
