Mr Joel Bertinshaw
Role at ANSTO
Joel Bertinshaw is a joint PhD student of the Bragg Institute and the University of New South Wales. His supervisors are Dr. Frank Klose at ANSTO and A/Prof. Clemens Ulrich, a joint appointee between the Bragg Institute and the School of Physics at UNSW.
His thesis involves the study of thin film heterostructures featuring strongly correlated electron systems, such as high temperature superconductors, multiferroics and colossal magnetoresistant materials, whose phenomena arise from a complex interplay between electron spin, orbit and charge, and the crystal lattice.
Neutron scattering techniques, in particular polarised neutron reflectometry, and Raman spectroscopy are essential tools in his research. Neutrons scattering is ideal for the study of atomic and magnetic structures and magnetic excitations, while Raman light scattering allows for precise measurement of electronic excitations and phonon modes.
He is also involved in the design and installation of the JOEY Neutron Laue Diffraction Alignment Instrument at the Bragg Institute. JOEY will aid scientists in the characterisation and alignment of single crystals, prior to scheduled beamtime on one of the Bragg Institute's high flux instruments.
Joel began work at ANSTO in 2008 as a part of the Graduate Development Program, created to skill the next generation of Australians to contribute to the international nuclear science and technology sectors, before beginning his PhD at the Bragg Institute in 2010.
He completed his honours project at the University of Technology, Sydney, supervised by A/Prof. Les Kirkup of the School of Physics and Advanced Materials at UTS, Prof. Matt Phillips of the Centre of Expertise Microstructural Analysis at UTS, and Frank Placido of the Thin Film Centre at the University of the West of Scotland. He investigated the post-deposition treatment of thin film systems of the transparent conductor indium tin oxide, used in LCD and OLED applications.
