RSPE undertakes a wide range of materials science research including:
Use of ion beams to modify both electrical physical properties of materials - especially semiconductors. The School has an 1.7MeV tandem accelerator dedicated to this purpose together with a number of smaller machines used for both modification of materials and diagnostic techniques such as RBS. This ion beam modification of semiconductors is complimented by a MOCVD growth program focusing on production of semiconductor optoelectronic devices such as quantum well lasers and detectors.
Design and development of advanced polymers and glasses for use in photonic devices such as all optical fibre amplifiers, nonlinear optical devices and planar wave-guides. The School has a laser direct write system for the production of prototype optical waveguide devices such as smart couplers. We also have facilities for production of optical fibre and a major program dedicated to novel fibre materials.
Interaction between materials occurs primarily at surfaces making the study of surface topology, physics and chemistry a priority area for the School. We also have several groups studying: interactions between solute particles, from molecules to proteins. Polymers in solution. Suspensions of colloidal particles. Such interactions determine the properties of most real world systems. Examples include self assembly of biomembranes, reactivity in biotechnologies and biochemistry, chemical synthesis, and a host of chemical engineering applications, from minerals processing, oil recovery to soil science and detergent formulation and drug delivery. In support of these activities we have several advanced diagnostic techniques such as ultra high-resolution computed tomography.
The School has a strong research effort in mechanochemistry: the use of physical impact to generate powders with unique physical properties especially on the nanoscale. Various processes techniques are being developed to create selective nanostructures in economically viable commercial quantities.
The School also has an active research program in ultra high speed laser ablation for both the modification of surfaces and the creation of exotic nanoscale ablation products such as ultra light carbon foams.

What is a granular material from geometry and physics perspective? We'll try to understand the fundementals of granular materials in this project.
Interest in biomimetic computing has led to interest in an excting new range of of solid-state neurons and synapses based on non-volatile resistive-switching and volatile threshold-switching in metal-oxide thin films. This project will explore the operation and functionality of these new devices.
This project will concentrate on developing metal contacts on nanowires for Hall measurements which will provide quantitative determination of the doping concentration and carrier mobilities in the nanowires, which is crucial to optimize performance of nanowire optoelectronic devices.
Phonon excitations will be modelled and measured using the neutron time-of-flight spectrometer PELICAN at the Bragg Institute, ANSTO.
