Based on the results of the first stage of the project, the methodology for the creation according to the scheme “forming-stabilization-functioning” of proper nanostructured inhomogeneities in CGGNC based on GC, GCH and GB with optimized characteristics for reproducible elements of optoelectronics, IR photonics, sensor and opto-telecommunication technics is substantiated.
