Abstract: Nanocrystals of metal sulfides (CdS, ZnS, CdZnS, CuS, and PbS) are formed upon the interaction of gaseous hydrogen sulfide with Langmuir—Blodgett films of metal behenates. To remove the organic matrix, the Langmuir—Blodgett films are annealed at temperatures of 130—350$^\circ$C. The morphology and structure of two-dimensional arrays of nanocrystals at both stages of synthesis are investigated by high-resolution transmission electron microscopy. These experimental data are used to qualitatively describe the formation of nanocrystals and the transformation of their structure and morphology in the context of the known classical and nonclassical mechanisms.
