Vanadium dioxide is the most promised thermochromic material for “smart windows” that switching reversibly infrared (IR) transmission in response to environmental conditions, reducing thus energy demand [1]. But important fundamental challenges have to be overcome for a wide application of VO2-based glazing that are (1) reduction of VO2 switching temperature and (2) increasing alteration of IR reflectivity, maintaining a high visible transparency. To reduce VO2 transition temperature, instead of traditional doping, which unavoidably decays transition width and sharpness, we apply a strain engineering approach. The tuning of material properties in nanocomposites through the manipulation of strains has been firstly demonstrated in our work [2]. To realize this approach for VO2 we utilize deposition of thin film consisted of VO2 nanograins epitaxially coupled with another oxide. Using a transparent oxide as second one enables also enhancing the visible transparency. The growth of epitaxially coherent two-phase nanocomposite is the principal technological problem especially in the case of an amorphous substrate. We apply here a solution based chemical technology of metalorganic aerosol deposition (MAD), which is cost-effective and scalable technique for further large-scale producing owing to its cheapness and readiness to integrate into float-glass fabrication line. Here we report on MAD growth of VO2 and SnO2 single phase films as well as two-phase VO2SnO2 composite films on amorphous substrates (fused silica and SiO2/Si(111)). We estimated oxygen pressure for a stable VO2 formation and obtained a pure SnO2 at the same conditions. Nanocomposite VO2-SnO2 films were then grown from a single solution contained both V and Sn metalorganic precursors. The crystal structure of the films was examined by x-ray diffraction, whereas the film thickness was estimated from x-ray reflection. A comprehensive analysis of surface morphology that was performed using atomic force microscopy (AFM) and scanning electron microscopy (SEM) reveals continuous films composed of homogeneously arranged nanocrystals with irregular shapes. Transition hysteresis behavior was examined by measuring temperature dependence of resistivity. The correlation between alteration of transition temperature and epitaxial relationship between nanocrystals are discussed. In summary, we have demonstrated that MAD technique allows fabrication of two-phase nanocrystalline thin films on amorphous substrates. By manipulating the growth conditions the transition temperature of the functional VO2 component can be varied, but range of the variation depends on appropriate selection and growth of the second oxide phase.
