Low Energy Electron Diffraction (LEED) with optional Auger Electron Spectroscopy (AES)

Low Energy Electron Diffraction (LEED) is one of the most powerful methods to determine surface structures. Analysis of LEED patterns and intensities provides the size and shape of the surface unit cell, the degree of order and detailed atomic structure with a precision of the order of picometers. Our LEED optics also enable Auger Electron Spectroscopy (AES) when equipped with the appropriate (optional) control unit. AES is a technique to provide chemical analysis of the surface. Our LEED optics are available in two flange sizes, DN100CF and DN150CF. We recommend the largest possible flange size if the chamber allows it, as larger screen sizes much are easier to work with and the cost saving for the smaller optics is minimal.
