  • Device and method for characterizing surfaces
    Patent number: 8232518
    Abstract: A method of characterizing surfaces comprises the steps of: directing a beam (2) of neutral atoms or molecules on a surface (3) for characterizing; and detecting in position-sensitive manner the neutral atoms or molecules of said beam that have been diffused forwards by said surface (3) for characterizing; the properties of said beam (2) being selected in such a manner that at least some of said neutral atoms or molecules that are diffused forwards are diffractive by said surface for characterizing. A device for implementing such a method comprises means (1) for generating such a beam (2) of neutral atoms or molecules and position-sensitive detector means (4) for detecting the neutral atoms or molecules that are diffused forwards by said surface (3) for characterizing.
