Article Description

Superconducting tantalum disulfide nanowires have been synthesised by surface-assisted chemical vapour transport (SACVT) methods and their crystal structure, morphology and stoichiometry studied by powder X-ray diffraction (PXD), scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and nanodiffraction. The evolution of morphology, stoichiometry and structure of materials grown by SACVT methods in the Ta–S system with reaction temperature was investigated systematically. High-aspect-ratio, superconducting disulfide nanowires are produced at intermediate reaction temperatures (650 °C). The superconducting wires are single crystalline, adopt the 2H polytypic structure (hexagonal space group P6/mmc: a = 3.32(2) Å, c = 12.159(2) Å; c/a = 3.66) and grow in the (Equation presented) direction. The nanowires are of rectangular cross-section forming nanotapes composed of bundles of much smaller fibres that grow cooperatively. At lower reaction temperatures nanowires close to a composition of TaS are produced whereas elevated temperatures yield platelets of 1T TaS. © 2010 The Royal Society of Chemistry.
