Spin-Polarized Two-Electron Spectroscopy of Surfaces, Softcover reprint of the original 1st ed. 2018 Springer Series in Surface Sciences Series, Vol. 67

This book presents developments of techniques for detection and analysis of two electrons resulting from the interaction of a single incident electron with a solid surface.  Spin dependence in scattering of spin-polarized electrons from magnetic and non-magnetic surfaces is governed by exchange and spin-orbit effects. The effects of spin and angular electron momentum are shown through symmetry of experimental geometries: (i) normal and off normal electron incidence on a crystal surface, (ii) spin polarization directions within mirror planes of the surface, and (iii) rotation and interchange of detectors with respect to the surface normal.  Symmetry considerations establish relationships between the spin asymmetry of two-electron distributions and the spin asymmetry of Spectral Density Function of the sample, hence providing information on the spin-dependent sample electronic structure. Detailed energy and angular distributions of electron pairs carry information on the electron-electron interaction and electron correlation inside the solid. The ?exchange ? correlation hole? associated with Coulomb and exchange electron correlation in solids can be visualized using spin-polarized two-electron spectroscopy. Also spin entanglement of electron pairs can be probed. A description of correlated electron pairs generation from surfaces using other types of incident particles, such as photons, ions, positrons is also presented. 

Sergey Samarin graduated from Leningrad State University in 1972 and completed his PhD studies of “radiative interaction of low-energy electrons with metals” in 1976. Then, as Research Fellow, Senior Research Fellow at the Institute of Physics, Leningrad State University (now St. Petersburg State University), he pursued further aspects of electron interactions with surfaces. From 1981-1984, as Associate Professor at the University of Conakry, Guinea, his accomplishments included fluency in French. After returning to St. Petersburg State University he continued his work on low-energy inverse photoemission from solid surfaces, total current spectroscopy, and plasmon excitation in thin Ag films by electron impact with their subsequent decay via photon emission. This work resulted in his Doctor of Science degree in 1995.  

From 1991-1992 and 1995-2000 Sergey Samarin enjoyed research as an invited Research Fellow in the group of Professor Kirschner in the Max Planck Institute for Microstructure Physics, Halle, Germany. The development there of low-energy spin-polarized two-electron spectroscopy of solid surfaces in reflection geometry, and its achievements, opened new avenues.   

In 2000 he moved to the University of Western Australia, as Research Fellow, Senior Research Fellow, and Research Professor combining his research with undergraduate and graduate teaching. His work was focused mainly on the interaction of spin-polarized low-energy electrons and positrons with solid surfaces for which new instruments were constructed in the Australian Research Council Centre of Excellence for Antimatter and Matter Studies at UWA.  Spin-dependent electron scattering dynamics and spin-related electronic properties of magnetic and nonmagnetic surfaces were studied using spin-polarized low-energy single- and two- electron spectroscopies.
