We report the synthesis of a novel branched nano-heterostructure composed of SnO2 nanowire stem and α-Fe2O3 nanorod branches by combining a vapour transport deposition and a facile hydrothermal method. The epitaxial relationship between the branch and stem is investigated by high resolution transmission electron microscopy (HRTEM). The SnO2 nanowire is determined to grow along the [101] direction, enclosed by four side surfaces. The results indicate that distinct crystallographic planes of SnO2 stem can induce different preferential growth dir...
