Functional Materials Group

Research Interests

Defects and diffusion solids, including ionic, molecular and polymeric materials; Electrical transport in polar solids; Solid electrolytes, (superionic or fast-ion conductors); Nanocystalline materials; Structural methods, including X-ray absorption fine-structure (XAFS) spectroscopy and NMR; Computer modelling of solids; Chemical sensor development. Real solids contain defects at the atomic level, termed point defects, and it is these defects which allow atoms to diffuse. The research in my group is aimed at understanding the structure of point defects and the mechanisms of diffusion, information important to a wide range of technological processes, including corrosion, catalysis and many materials processing methods. The work of the group encompasses a broad spectrum of material types, from single crystal, inorganic solids to organic polymers, and employs a wide variety of techniques, including materials synthesis, electrical measurements, radiotracer methods, NMR, synchrotron radiation, neutron scattering and computer modelling.
