AbstractPalladium nanoclusters produced in an inert gas aggregation/magnetron sputtering source are being used as building blocks for the construction of nano electronic devices with large surface to volume ratios that can be used as sensitive hydrogen gas sensors in fuel cells and in petrochemical plants. Grazing incidence X-ray diffraction (GIXRD) at the Stanford Synchrotron Radiation Laboratory (SSRL) and high resolution transmission electron microscopy (HRTEM) have been used to characterise the structure, lattice constant, particle diameter and oxide thickness of the palladium nanoclusters in order to understand the operation of these sensors. © 2007 Science Reviews 2000 Ltd.
