Photoelectron spectroscopy and the future of surface analysis Faraday Discussion

Wendy Flavell is Professor of Surface Physics at the University of Manchester, UK. She trained initially in inorganic chemistry in Oxford (DPhil) and at Imperial College London (Royal Society URF).  Her research is focussed on the electronic structure of functional materials including semiconductor nanocrystals, oxide catalysts and photocatalysts, tackling questions such as 'how can we make solar cells cheaper and more efficient?'  Much of this work uses photoelectron spectroscopies, including near-ambient-pressure techniques, time-resolved photoemission, depth-profiling approaches using synchrotron radiation and lab-based hard X-ray photoelectron spectroscopy.  Wendy is a reviewer of programmes for several international accelerator-based light sources including MAX IV (Sweden), and is a member of the Physics sub-panel for REF2021. 

Anders Nilsson received a PhD in physics at Uppsala University, Sweden (1989) in the laboratory created by the Nobel Laureate Kai Siegbahn. Before returning to Sweden in 2014 he was 15 years as a professor in Photon Science at Stanford University. His research interests include x-ray spectroscopy and scattering, chemical bonding and reactions on surfaces, ultrafast science, heterogeneous catalysis, electrocatalysis in fuel cells, photocatalysis for converting sunlight to fuels, structure of water and aqueous solutions.
 
He received the Lindbomska Award at the Swedish Royal Academy of Science, the Royal Oscar Award at Uppsala University, the Shirley Award in Berkeley, the Humboldt Award for senior scientist in Germany and was awarded Honorary Doctorate at Denmark’s Technical University.  The research on water was selected in 2004 by Science Magazine as one of the top ten breakthrough of the year, illustrated in 2014 as cover of Nature and selected as one of the 100 most essential discoveries in 2017 by Discovery Magazine.

Dr. Martina Dell’Angela received her PhD in physics at University of Trieste (Italy) in 2009. She has been post Doc at University of Hamburg/CFEL in the group of Prof. Wilfried Wurth from 2010 to 2013 and she studied ultrafast chemical reactions with time-resolved X-ray techniques at X-ray free electron laser sources in a joint collaboration with Prof. Anders Nilsson. From 2013 to 2015 she has been post Doc in the group of Prof. Fulvio Parmigiani at the FERMI FEL (Elettra, Italy) and contributed to the design and construction of a RIXS endstation. In 2015 she started her independent career research thanks to a young investigator grant (SIR) from the Italian Ministry of Research. Currently she is permanent researcher at ‘Istituto Officina Dei Materiali’ (IOM) of the Italian National Research Council. She applies time resolved spectroscopies with synchrotrons and X-ray lasers to the study of exciton dynamics in photovoltaic materials.

Giulia Galli is the Liew Family professor of Electronic Structure and Simulations in the Pritzker School of Molecular Engineering and Professor of Chemistry at the University of Chicago. She also holds a Senior Scientist position at Argonne National Laboratory, where she is a group leader and the director of the Midwest Integrated Center for Computational Materials (http://miccom-center.org/).  She is an expert in quantum simulations of materials and molecules and her research focuses on problems relevant to the development of sustainable energy sources and quantum technologies (https://galligroup.uchicago.edu/). She is a member of the US National Academy of Sciences, the American Academy of Arts and Science, and the International Academy of Quantum Molecular Science.

Dr Olivier Renault is team leader of the Surface Analysis group at the Nanocharacterization Platform of CEA-Leti since 2006. His activities deal with photoemission techniques and analytical methods for device technology and related materials, including X-ray photoelectron spectroscopy (XPS), hard X-ray photoelectron spectroscopy (HAXPES) and photoemission electron microscopy (PEEM) for elemental, chemical, work function and band structure imaging, with at times the use of synchrotron radiation. He joined Leti in 2000 after a PhD degree from Grenoble Polytechnical Engineering Institute and a post-doctoral stay at the University of Oxford, UK (Physical Electronics Group, Department of Engineering Science). Since 2015 he has been involved in the organization of events related to photoemission, such as the Focus Topic “Novel Trends in Light Sources” at the Annual Symposium of the American Vacuum Society, and the Photoelectron Spectroscopy Annual Workshop of the French Vacuum Society.

Dr. Mathieu G. Silly is beamline Scientist at the TEMPO Beamline at the Synchrotron Soleil in France, since 2008. He is in charge with the development of pump probe experiment using high resolution photoemission spectroscopy to study transient phenomena in photoexcited materials. He was graduated from “Institut d’Optique Graduate School” (France) in 2000 and received his PhD Degree in surface science in 2004 from University of Paris XI (France). In 2005, he worked as a postdoc fellow at the ONERA on the optical properties of hBN wide band gap 2D semiconductor. He joined the synchrotron SOLEIL in 2006 to develop the time resolved photoemission spectroscopy on the TEMPO beamline. After being co beamline manager in 2017, he has been appointed head of LASER installation at the TEMPO beamline. His main research interests include the optical, electronic and chemical properties of 2D and nano materials.

Dr. Kelsey A. Stoerzinger joined Oregon State University as an Assistant Professor and Callahan Faculty Scholar in the School of Chemical, Biological and Environmental Engineering in the Fall of 2018. She holds a joint appointment at Pacific Northwest National Laboratory, where she was a Linus Pauling Distinguished Postdoctoral Fellow. Kelsey completed her doctoral studies in Materials Science and Engineering in 2016 from the Massachusetts Institute of Technology, supported by a National Science Foundation Graduate Research Fellowship. She received an M.Phil. in Physics from the University of Cambridge as a Churchill Scholar and a B.S. from Northwestern University. Prof. Stoerzinger is the recipient of the NSF CAREER Award (2020) and the Doctoral New Investigator Award of the ACS-PRF (2019), in addition to recognition for her contributions as a teacher and advisor.
