25. Conclusions 1. Quantum-dimensional effects allow to create devices based on the new physical phenomena, with improved properties; 2. The creation of such devices is only possible using sophisticated technology usually called «high-technology» 3. The quantum-dimensional nanostruc- tures are the main basis of the scientific- technical progress in such important areas like solid state lighting, optical memory, and nanoelectronics.
