Tuning the morphology of SrTiO3 nanocubes and their enhanced electrical conductivity
تنظیم مورفولوژی نانومکعب های SrTiO3 و هدایت الکتریکی افزایش یافته آنها-2021 Strontium titanate (SrTiO3) nanocubes were prepared via the solvothermal method in an isopropanol-water
system, using cetyltrimethylammonium bromide (CTAB) as a capping agent and tert-butylamine (TBA) as a
mineralizer. We found that the presence of TBA produced a synergistic effect in the nucleation and growth of
SrTiO3 in the solution, which enabled control over the formation of well-defined cubic particles. X-ray diffraction
patterns of SrTiO3, synthesized with the addition of 1 mol of TBA, showed a perovskite structure with high
crystallinity. The presence of specific absorption peaks in the fourier-transform infrared (FTIR) spectrum
confirmed the existence of CTAB and TBA on the surface of the particles. Transmission electron microscope
(TEM) images showed that the sharp-edged cubic particles had narrow size distributions, and selected area
electron diffraction (SAED) patterns indicated a high crystallinity. An increase in electrical conductivity values
was found in the bulk samples with regular nanocube particles compared to those of non-regular nanocubes.
