About the Project

The development of new technologies often hinges on the possibility to design novel functionalities in advanced functional materials. The integration of such materials in devices often requires epitaxial thin films where the control of interfaces and strain is essential as small changes in the crystal structure can have a drastic impact on the physical properties. Unfortunately the tools required to probe such minute changes at the atomic scale have so far required destructive methods such as high resolution transmission electron microscopy where only a small volume of the sample is analysed giving a local picture of the system.

In this project we propose to determine the crystal structure of a complex inorganic oxide material BTFM-CT and the possible strained stabilised phases in epitaxial thin films using advanced x-ray scattering methods (Crystal Truncation Rods and Coherent Bragg Rod Analysis) and correlate it to the observed functionalities.

The project proposed will highlight the use of epitaxial thin films as viable route to determine crystal structure when powder diffraction fails to give a clear solution and bulk single crystals are not available. The development of a software implementing the COBRA algorithm will be highly beneficial to the oxide thin film community by providing a tool similar to what is available to bulk inorganic material researcher and will encourage a more in-depth understanding of the crystal structure of hetero-epitaxial films.

Career overview

Professor Matthew Rosseinsky studied Chemistry at the University of Oxford, where he received a BA in 1987 and a D. Phil in 1990. Following his studies, he joined A.T.&T. Bell Laboratories in Murray Hill, New Jersey, as a Postdoctoral Member of Technical Staff. In 1992, he returned to Oxford as a Lecturer in Inorganic Chemistry and a Student (Fellow) of Christ Church. In 1999, he moved to the University of Liverpool, where he holds the position of Professor of Inorganic Chemistry. Throughout his career, Professor Rosseinsky has received numerous awards, including the Harrison Memorial Prize in 1991, the Corday-Morgan Medal and Prize in 2000, and the Tilden Lectureship in 2006 from the Royal Society of Chemistry (RSC). In 2009, he was honoured with the inaugural De Gennes Prize from the RSC, recognising his lifetime achievements in materials chemistry. He has served as a Distinguished Lecturer in Inorganic Chemistry at Northwestern University in 2006, a Zernike Lecturer at Rijksuniversitat Groningen in 2009, and received the C.N.R. Rao Award from the Chemical Research Society of India in 2010. In 2017, he was the Muetterties Lecturer at the University of California, Berkeley, and the Lee Memorial Lecturer at the University of Chicago. In 2008, Professor Rosseinsky was elected to the Royal Society and was awarded the Hughes Medal in 2011 for his influential discoveries in the synthetic chemistry of solid-state electronic materials and novel microporous structures. He became a Royal Society Research Professor in 2013 and received the Davy Medal in 2017 for his advances in the design and discovery of functional materials, integrating new experimental and computational techniques. He was a member of the Science Minister’s Advanced Materials Leadership Council from 2014 to 2016 and served on the governing Council of the Engineering and Physical Sciences Research Council from 2015 to 2019. In 2019, he delivered the Flack Memorial Lectures for the Swiss Crystallographic Society and was awarded the Frankland Lectureship by Imperial College London. In 2020, he became an Honorary Fellow of the Chemical Research Society of India. In 2022, he presented the Davison Lectures at the Massachusetts Institute of Technology and received the Basolo Award from the Chicago Section of the American Chemical Society. In 2023, Professor Rosseinsky was awarded the Eni Energy Frontiers Award for the digital design and discovery of next-generation energy materials by the President of Italy.


Research interests

Professor Rosseinsky leads a research group focused on the design, discovery, synthesis, and characterisation of solid state materials. His work aims to enhance the fundamental understanding of the physical and chemical properties of new materials while improving their performance for applications in energy storage and generation, communications, and catalysis. He has made influential discoveries in the synthetic chemistry of solid state electronic materials and novel microporous structures.
