description: The final qualification work is devoted to the study of the structure of nanowhiskers of copper oxide (tenorite) formed during thermal oxidation in air of the copper coating. Special attention was paid to linear, two-dimensional and threedimensional structural defects. A literature review is presented, which shows the prospects of using nanowhiskers in various industries. Previously obtained transmission electron microscopy data on the defective structure of nanocrystals are considered, as well as various models of their formation are considered. The analysis of the available structural data is carried out, and the need to continue the research of nanocrystals using a wider range of electron microscopy methods is shown. The nanowhiskers of copper oxide studied in the qualification work were grown at Togliatti state University. Experimental data were obtained using the equipment of the shared services center "Materials Science and diagnostics in advanced technologies", which operates on the basis of the Ioffe Institute. In the preparation of samples, the cross-section method was used, which was previously practically not used for structural studies of nanocrystals. The structural state was studied by transmission electron microscopy in three modes on two devices. In the diffraction contrast and microdiffraction modes, the study was performed using a PHILIPS EM420 electron microscope with an accelerating voltage of 100 kV, and in the microdiffraction and high resolution modes, using a JEOL microscope (200 kV). The efficiency of using the cross-section method for the study of nanostructures with a large aspect ratio is demonstrated. It is shown that nanowhiskers have a bi-or polycrystalline structure with a growth direction along the axis [ 1 1 Ì0 ]. Orientation relations between their components and the mechanism of formation of these relations are revealed. The habitus of nanocrystals is established. Based on the structural data, an assumption is made about the ways of transport of copper ions to the growth surface of the nanocrystal.
