Description
An amorphous ultra thin W foil with a thickness of 2 nm was deposited on an amorphous 3 nm carbon foil by electron beam- physical vapor deposition. The specimen was analyzed in an aberration corrected scanning transmission electron microscope (STEM) under ultra high vacuum condition. During the observation the amorphous structure of W converts to a partially nanocrystalline structure. The crystal phase structures are analyzed by Fast Fourier Transformation calculated from high angle annular dark field (HAADF) images. In addition, the surface diffusion of W atoms could be observed and measured in continuously acquired HAADF images.
