This book summarizes the most recent and compelling experimental results for complex oxide interfaces. The results of this book were obtained with the cutting-edge photoemission technique at highest energy resolution. Due to their fascinating properties for new-generation electronic devices and the challenge of investigating buried regions, the book chiefly focuses on complex oxide interfaces. 


The crucial feature of exploring buried interfaces is the use of soft X-ray angle-resolved photoemission spectroscopy (ARPES) operating on the energy range of a few hundred eV to increase the photoelectron mean free path, enabling the photons to penetrate through the top layers – in contrast to conventional ultraviolet (UV)-ARPES techniques. The results presented here, achieved by different research groups around the world, are summarized in a clearly structured way and discussed in comparison with other photoemission spectroscopy techniques and other oxide materials. They are complemented and supported by the most recent theoretical calculations as well as results of complementary experimental techniques including electron transport and inelastic resonant X-ray scattering.

Dr. Vladimir N. Strocov graduated from St. Petersburg State University, Russia in 1986 and obtained his PhD degree there in 1990 with specialization in solid-state physics. His further experimental and theoretical research in a number of European institutions (Chalmers University of Technology, Sweden, University of Augsburg, Germany etc.) focused on photoelectron and very-low-energy electron diffraction spectroscopies applied to a wide range of solid-state systems ranging from bulk to nanomaterials. He obtained his habilitation degree in 2000 with the Institute for Analytic Instrumentation in St. Petersburg, Russia. His present activity at the Swiss Light Source since 2004 extends from the development of synchrotron radiation instrumentation to research on various bulk and nanostructure solid-state systems with different electron correlation strengths using soft X-ray photoelectron spectroscopy and related techniques. He has more than 125 publications in refereed journals and monographs, including 24 publications in Physical Review Letters, 6 in the Nature journals and 3 invited reviews, and has been a guest editor in a number of topical journal issues.
