Abstract

In this work, we have successfully synthesized cubic MASnI3 halide-perovskite on a SnO2 nanowire through two-step process using a chemical vapour deposition (CVD) system. First, SnO2 nanowires with diameter in the range of 15 to 50 nm were fabricated via thermal oxidation process with Au catalyst at 800ºC. A SnO2 nanowire was used as a template for the growth of MASnI3 cubics in the second step. The obtained products were characterized by X-ray diffraction (XRD), field-emission electron scanning microscopy (FE-SEM), and high-resolution transmission electron microscopy (HR-TEM). Finally, the formation mechanism of the MASnI3/SnO2 hybrid was discussed in detail.
