Research summary

Current research topics within the group include the following.

Materials and interfaces in power electronics

We work on both established and new generations of wide band gap materials for power electronics, including e.g. SiC and Ga2O3. Beyond investigating bulk properties of different crystal polymorphs and thin films orientations we are particularly interested in the study of interfaces in power electronics using X-ray spectroscopy.

Sol-gel methods for thin films

We focus on developing sol-gel deposition methods for thin films of transparent conducting oxides (TCOs), a class of materials widely applied in device and display applications, including photovoltaics and LEDs. We develop and optimise deposition methods for high quality, doped ultra thin films of post-transition metal oxides. This is important to enable applications of new TCOs in devices as well as to enable the use of advanced characterisation techniques, were the ability to create high quality, highly ordered samples is of great advantage. We are particularly interested in the relationship between morphology, crystal structure, and electronic structure of these films to develop a complete understanding of the materials' characteristics and ultimately their device behaviour.

Inorganic materials for biosensors

The group is involved in a Newton Fund project (CHIRP), which aims to develop a new Point of Care platform for glucose sensing based on oxide nanostructures rather than enzymes. Our main aim is to further develop existing synthesis routes for oxide nanostructures. A wide range of syntheses has been proposed in the literature but we greatly lack understanding of how synthesis parameters influence the morphology and surface chemistry of the resulting nanostructures.

Hard X-ray Photoelectron Spectroscopy (HAXPES)

HAXPES is one of the most powerful techniques to study local chemical states and electronic structure of devices. The high X-ray energies used enable larger depth information, making it possible to study buried layers and interfaces in devices. We work closely with Scienta Omicron developing their new laboratory-based HAXPES system. In addition, we collaborate with beamline I09 at Diamond Light Source in trialling new measurement strategies and developing new in-situ and in-operando approaches to apply HAXPES to the often complex structures found in devices.

X-ray radiation damage

As we are heavy users of X-ray based techniques, including spectroscopy and diffraction, the question of how X-rays interact with matter is of great importance to us. Whilst X-ray radiation damage is well understood in biological systems, hardly anything is known about this effect in small molecular crystals and inorganic materials. We are part of a group of collaborators stretching from laboratory to synchrotron techniques, X-ray diffraction to X-ray spectroscopy, and experiment to theory, which is trying to establish a fundamental understanding of how the reaction of matter under X-ray radiation can be understood and what we can learn about the material itself.

Biography

Anna Regoutz is a Lecturer in Materials Chemistry in the Department of Chemistry at University College London. She is a CAMS-UK Fellow and holds a Visiting Scientist position at Diamond Light Source. Her research focus lies on bulk, thin film, and nano materials for application in devices, including power electronics, photovoltaics, and biosensors. Her interests include novel growth methods for high quality thin films, nanostructured layers, and nanostructures of inorganic materials with a focus on metal oxides. She works on developing and advancing X-ray spectroscopy methods for bulk materials and surfaces/interfaces in electronic devices. She concentrates on using and developing both laboratory- and synchrotron-based spectroscopic methods to study in particular the electronic structure in oxide heterostructures. Anna uses her combined expertise in deposition and characterisation of these materials to understand and tune the materials' electronic and optical characteristics to ultimately improve existing device concepts and develop novel device applications.

Anna received her BSc (2009) and Dipl. Ing. (2010) from the Graz University of Technology, Austria. During the Masters programme (Dipl. Ing.) she concentrated on “Surface and Interface Technologies”. Whilst studying at Graz she worked at Infineon Technologies Austria, Villach, Austria, where she conducted research for her Masters thesis titled “Evaluation of Decapsulation Methods for Semiconductor Devices”. She conducted her D.Phil. research in Inorganic Chemistry between 2010 and 2014 under the supervision of Prof. Russell Egdell at the University of Oxford, UK, and Trinity College, Oxford, UK. The research focused on structural and electronic properties of metal oxides. During the academic year 2012/13 she held a non-stipendiary lectureship in Inorganic Chemistry at Lady Margaret Hall, Oxford, UK.

Anna held an an Imperial College Research Fellowship between 2017 and 2019 in the Department of Materials at Imperial College London. Anna is a member of the Royal Society of Chemistry (MRSC), the Institute of Physics (MInstP), the Institute of Materials, Minerals and Mining (IOM3), the Materials Research Society, and of the Society of Austrian Chemists GÖCH. She currently serves as a co-opted member of the Dielectrics and Electrostatics Group committee of the IoP and as a member of the Solid State Chemistry Group committee of the RSC. In 2018 she was awarded the Student Academic Choice Award for Best Teaching for Undergraduates at Imperial. In 2019 she was awarded the element Praseodymium in the Periodic Table of Chemists by the IUPAC. Anna is an Associate Editor in the Understanding the Earth and its Resources section of Frontiers for Young Minds, an open-access scientific journal written by scientists and reviewed by children. Anna serves on the editorial board of Quantum Beam Science.
