Mechanism of nanofragment formation in A2VB3VI-type crystals


Ways to improve the degree of ordering of self-organized nanoobjects in A2VB3VI<impurity> systems are discussed. It is shown that, as a result of diffusion intercalation during crystal growth, it is possible to combine the methods of vertical directional crystallization with additional migration of atoms (Cu, Ni, Zn, In, Se,) into the interlayer space and defect cavities. Apparently, stress relaxation between quintets occurs through the mechanisms of elastic and plastic deformation with mass transfer and the appearance of screw dislocations, which affects the nature of folded-corrugated submicrostructures and the distribution density of nanoislands. Nanoislands and fold formations are evidenced by AFM images in 2D and 3D scales.

Keywords: layered crystals, plastic deformation, mass transfer, self-organized nanoobjects, corrugated microstructures.
