Long Bio

Ernst Bauer main contributions are: classification of thin film growth and nucleation mechanisms and his invention in 1962 of the Low Energy Electron Microscopy (LEEM), which came to fruition in 1985. In the early 1990s, he extended the LEEM technique in two directions by developing Spin-Polarized Low Energy Electron Microscopy (SPLEEM) and Spectroscopic Photo Emission and Low Energy Electron Microscopy (SPELEEM). Numerous LEEM instruments are now installed and are operating in many laboratories and synchrotron radiation facilities around the world (USA, Europe, Asia).
