A High-Throughput Neutron Spectrometer for The Study of Atomic and Molecular Motion at ANSTO. Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed.

Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of option to an existing spectrometer that will broaden its user-base from specialised applications in physics to more general applications in physics, chemistry, materials-science and biology. This additional option provides a totally new way for Australian scientists to study atomic and molecular motions. Read moreRead less
The best of both worlds: electrically detected optical spectroscopy at the single atom limit. One atom, one photon, one electron, in a silicon crystal. We will demonstrate a novel technique to detect the absorption of light by a single atom, in the most significant environment for nanoelectronics and photovoltaics. Our technique will help unravel how light is turned into electricity at the most microscopic and fundamental level.

Summary
High pressure facility for optical spectroscopy: investigation of novel superconductors and strongly correlated electron systems. Superconductivity is an effect where the electrical resistance disappears completely at low temperatures. This facility will permit optical spectroscopy under high hydrostatic pressure to reveal important new information leading to a deeper understanding of this effect.

Ultrafast time resolved optical spectroscopy for advanced multifunctional materials: Time resolved spectroscopy is among the hottest emerging fields in condensed matter physics and offers a new perspective into the complex physics of multifunctional materials like multiferroics or unconventional superconductors. At present, the underlying physics of these novel complex materials is not fully understood and new experimental approaches such as the proposed time-resolved optical spectroscopy are required. The deeper understanding of the involved phenomena would also allow for a systematic search for new, undiscovered multifunctional materials with similar but enhanced properties. This offers a huge potential for future industry in applications such as in novel sensors, information processing, and high efficiency photovoltaics.Read moreRead less

Recent advances in growth methods such as pulsed laser deposition enable layer-by-layer growth with atomic precision. The aim of this project is to combine complementary experimental methods (ie neutron scattering and optical spectroscopy), in order to gain a detailed insight into the magnetic and electronic properties of the heterostructures. This is designed to yield a deeper understanding of the underlying physics in order to help develop new materials for next-generation information technology.Read moreRead less
Understanding how atomic-scale boundary conditions define the interaction of light with matter. Scientists are trying to mimic nature's ability to grow crystals into useful shapes. This project will measure the arrangement of atoms in a nanoparticle and see how this arrangement affects its colour. It will allow us to grow nanoparticles of the shape and colour we require for applications in medicine, sensing and electronics.

Locating Atoms by Observing Crystallographic Phase. Atomic structures are determined by measuring how they scatter radiation. However half of the necessary information, the crystallographic phase, cannot be measured from the scattered intensity. For a century the only option has been to deduce the phase via the statistical analysis of thousands of intensity measurements.

Atomic structures are determined by measuring how they scatter radiation. However half of the necessary information, the crystallographic phase, cannot be measured from the scattered intensity. For a century the only option has been to deduce the phase via the statistical analysis of thousands of intensity measurements. This project aims to develop a method to determine atomic structures from the direct observation of phase. From a handful of observations and no formal measurements, atoms can be located with picometre precision. It is predicted that this method will be direct, rapid and unequivocal, sensitive to light atoms and applicable to nanostructures, which will represent a paradigm shift in crystallography.Read moreRead less
