The nature of the interaction between gold and solutions containing lead has been investigated. An ultra high vacuum system was adapted for use with an electrochemical chamber. Glassware was designed and a process developed to ensure the clean gold surface remained clean enough for analysis during its exposure to solutions. Underpotential deposition was utilised to deposit small quantities of lead onto a gold single crystal surface. The deposited layers were analysed using Low Energy Electron Diffraction and X-ray Photoelectron Spectroscopy. A new structure, c(2x2), was discovered during t

Growing environmental concerns, coupled with increasing regulatory restrictions, are requiring industries to develop non-lead-based compositions of ferroelectric and piezoelectric materials. These materials—now widely used in sensors, actuators, and transducers—are for the most part lead-based compounds such as Pb(Zr,Ti)O3 (PZT). Indeed, PZT represents the dominant market share for use in these technologies. Moreover, next generation compounds, which include Pb(Mg1/3Nb2/3)O3-xat%PbTiO3 (PMN-x%PT) crystals with ultrahigh piezo-/electromechanical properties, are also Pb-based systems and thus ar

Metal halide perovskites have demonstrated great potential in energy and optoelectronic device applications, due to their excellent optoelectronic properties. Among all the forms of halide perovskites, single crystals have attracted increasing research interest because of their longer carrier diffusion length, larger charge carrier mobility, and superior stability. However, the practical applications for the bulk perovskite crystals have been limited because of their large thickness and the difficulty of integration.

The demands for high density, fine pitch interconnections in electronics systems has seen solder-based approaches for such interconnections miniaturized to the scale of tens of micro meters. At such a small scale, such 'micro joints' may contain only one or a few grains and the resultant mechanical behaviour may not be that for a polycrystalline aggregate, but rather for a single crystal. Since the ~-Sn matrix of SnAgCu solder has a contracted body-centred tetragonal (BCT) structure, such a solder grain is expected to demonstrate a considerably anisotropic behaviour.
