摘要: The development of STEM is outlined from the first developments by Baron Manfred von Ardenne, through successful field emission gun Albert Crewe and his collaborators, to its widespread application today in era aberration correction. review focuses on understanding incoherent imaging electron energy loss spectroscopy at atomic resolution will not include details microanalysis, low imaging, or specialized modes such as cathodoluminescence. Although it attempts cover all major advances approximately chronological order, undoubtedly there are omissions an overemphasis that author most familiar with own history.
