About Sergey
Sergey Samarin is a professor in the School of Physics, Mathematics and Computing at the University of Western Australia, holding the position of Senior Honorary Research Fellow. He earned his M.Sc. in Physics from St. Petersburg State University in 1972 with a thesis on the growth and ellipsometry study of thin films, followed by a PhD in Physics in 1976 on low energy electron interactions with Ta(111) surfaces, and a Doctor of Science degree in 1995 on low energy radiative-capture electron spectroscopy of metal, dielectric, and semiconductor surfaces, all from St. Petersburg State University. His career began as a Researcher and progressed to Senior Researcher at St. Petersburg State University from 1976 to 1995. He served as Senior Lecturer at the Faculty of Science, University of Conakry, Guinea from 1980 to 1984, and as Visiting Scientist in Prof. J. Kirschner’s Experimental Department at the Max-Planck Institute for Microstructure Physics, Halle, Germany from 1993 to 2000. Since joining UWA around 2000, he designed and built the new (e,2e) instrument for surface science applications in 2001 and co-leads the UWA positron facilities, an AINSE External Facility, with Prof Emeritus Jim Williams.
Samarin's research focuses on surface science, including surface electronic structure, adsorption phenomena, thin film growth, and electron scattering dynamics. His expertise encompasses electron spectroscopy techniques such as electron energy loss spectroscopy, Auger electron spectroscopy, spin-polarized two-electron spectroscopy, and photoelectron spectroscopy, along with ultra-high vacuum systems, magnetic nanostructures, and the electronic structure of nano-systems and thin films. He has applied positron annihilation lifetime spectroscopy to study materials like Nb-doped TiO2, SnO2, ZrO2, ultrafine-grained aluminum, polymer blends, off-stoichiometric Zn2TiO4, and natural diamonds. Key publications include 'Two electron photoemission in solids' (Physical Review Letters, 1998), 'Study of vacancy-type defects by positron annihilation in ultrafine-grained aluminum severely deformed at room and cryogenic temperatures' (Acta Materialia, 2012), 'Angle resolved energy correlated coincidence electron spectroscopy of solid surfaces' (Physical Review Letters, 1995), 'Visualizing spin-dependent electronic collisions in ferromagnets' (Physical Review Letters, 2000), and the edited volume 'Spin-Polarized Two-Electron Spectroscopy of Surfaces' (2019). He edited the latter book based on developments from his work at UWA.
