    Title: Experimental Studies of Atomic Step Contrast in Reflection Electron Microscopy (REM)
    Authors: Tung Hsu;L.-M. Peng
    教師: 徐統
    Date: 1987
    Publisher: Elsevier

    Atomic Step Contrast
    Reflection Electron Microscopy
    Abstract: One-atom-high steps on crystal surfaces have been observed with the Reflection Electron Microscopy (REM) technique. Strong focus-dependent contrast suggests that it is basically phase contrast. In this experimental work we studied the contrast of atomic steps under combined and separated Bragg condition and resonance condition. It is observed that although the resonance condition strongly affects the intensity of the images, the usual phase contrast features are observed only if the Bragg condition is satisfied.
