Abstract


The method of molecular layering − atomic layer deposition with varied conditions of synthesis has been used to obtain two- and tree-dimensional nanostructures of vanadium dioxide on single-crystal silicon surface. A growth mechanism for nanostructures of various dimensionalities has been proposed based on the data of atomic force microscopy. The magnetic and electrical properties of obtained samples have been studied by magnetic susceptibility and impedance spectroscopy methods. The semiconductor-metal phase transition in the nanosized vanadium dioxide on the silica surface has been found to occur at a reduced temperature as compared with that typical of the bulk.
