Successful structure determination entailed the development of adjustable parameter free self-consistent phase shifts, which provide a more reliable description of the electron scattering than traditional approaches. Additionally, the impact of soft surface vibrational modes on the structure determination has been investigated.

It seems that you're in Germany. We have a dedicated site for Germany. Numerous illustrations illuminate the fundamental aspects of the electron optics, the experimental setup, and particularly the application results with these instruments. Surface Microscopy with Low Energy Electrons will give the reader a unified picture of the imaging, diffraction, and spectroscopy methods that are possible using low energy electron microscopes. Professor Ernst Bauer is a distinguished German-American physicist and surface scientist who has made fundamental contributions to the understanding of epitaxial growth and to the development of microscopy techniques. He is one of the founders of surface physics and the physics of thin films.

Low-energy electron diffraction LEED is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low energy electrons 20— eV [1] and observation of diffracted electrons as spots on a fluorescent screen. An electron diffraction experiment similar to modern LEED was the first to observe the wavelike properties of electrons, but LEED was established as an ubiquitous tool in surface science only with the advances in vacuum generation and electron detection techniques. The theoretical possibility of the occurrence of electron diffraction first emerged in when Louis de Broglie introduced wave mechanics and proposed the wavelike nature of all particles. The de Broglie hypothesis was confirmed experimentally at Bell Labs in when Clinton Davisson and Lester Germer fired low-energy electrons at a crystalline nickel target and observed that the angular dependence of the intensity of backscattered electrons showed diffraction patterns.

We apologize for the inconvenience...

A "LEEM low energy electron microscope " is an instrument to obtain a surface image of a specimen. The incident electron energy is reduced to several V to several 10 V, and elastically-backscattered electrons from a specimen are accelerated by an electric field just above the specimen. The formed image is enlarged by the imaging lens and observed through a screen or a camera.

Вопрос был лишь в том, насколько мощным. Ответ получили через двенадцать минут. Все десять присутствовавших при этом человек в напряженном ожидании молчали, когда вдруг заработавший принтер выдал им открытый текст: шифр был взломан.
