We discovered a method for growing vertically aligned bundles of Mo6S9-xIx (4.5< x < 6) nanowires perpendicular with respect to the substrate. In this efficient method, one step synthesis direct from molybdenum, sulphur and iodine in the temperature gradient conditions is used. The bundles with similar lengths and diameters could be grown on quartz or conductive materials like molybdenum foil at the temperature around 1040 K. This material could be potentially used for some applications like as building blocks in nanodevices.

Mo6S3I6 nanowire networks of interest are found to change their resistance in response to the presence of analyte vapors. The vapor sensing behavior is quantitatively described very well phenomenologically in terms of the concentration of adsorbed analyte molecules in the contact tunneling junctions, and an expression is derived for the dynamics and sensor resistance in terms of analyte vapor pressure. The time response of the sensor is observed to follow simple adsorption-desorption kinetics. The response function favors rapid detection of small analyte concentrations.
