Electron Channeling at Ultra-High Voltages and Its Applications to Materials Science

Abstract

Since 1963–65, high voltage electron microscopes and their related accessaries have been rapidly developed and widely applied to the materials science, especially in Japan. Various sorts of in-situ experiments have been carried out with these electron microscopes in addition to precise characterization and identification of microstructures. Furthermore, recently new research fields named “high-energy electron beam science and engineering” have been developed with ultra-high voltage electron microscopes, and in-situ formation of new functional materials such as non-equilibrium phases has also been made possible.
This account deals with great advantages of ultra-high voltage electron microscopy and its applications to the aforementioned new research fields in materials science.
