The metal-insulator transition (MIT) in VO2 is of both fundamental and technical interest, the former due to important questions about its origins, and the latter due to possible applications in electronic devices such as ultrafast optical switches and field effect transistors. In bulk VO2, a large structural distortion accompanies the conductivity transition from the metallic (rutile) to the...

We are exploring the use of atomically-precise, chemically-synthesised metal clusters deposited on various forms of oxides with a view to understanding how and why they perform as catalysts and sensors.1, 2 Although measurement of their catalytic activity is important, it is vital to identify and understand the geometric and electronic structure of the active sites to make further gains in...
145. Observation of crystalline orthogonal self-stratification in spin-coated conjugated polymer thin films with depth-sensitive X-ray scattering
Dr Eliot Gann (Australian Synchrotron)
We report the observation of an orthogonally realigned crystalline surface layer in a spin-coated conjugated polymer film as used in organic field-effect transistors. The ability of Grazing Incidence Wide Angle X-ray Scattering to provide some surface sensitivity of scattering features within thin films is known, but until now an unambiguous orthogonal stratified crystalline microstructure in...
180. Synthesis and Characterisation of (M1-xFex)2SnO4 (M = Mn, Co, Zn) ternary transition metal-tin-oxygen spinel systems
Dr Tilo Soehnel (The University of Auckland)
Mixed transition-metal oxide (MTMO) spinels including Mn and Zn-metal containing stannate phases have promising material properties and are known for the ability to tailor particular features for different uses. They are currently being explored as possible alternative substrates in many emerging high-tech applications such as electrode materials in lithium-ion batteries and as conducting...
