摘要: Abstract The growth dynamics of polycrystalline Ge clusters during annealing GeAg co-sputtered films was studied by employing in-situ transmission electron microscopy and Auger spectroscopy. During crystallization a-Ge, up to 2 μm in diameter, surrounded the Ge-depleted zones about 100 nm width, grew laterally on film plane as a result surface segregation Ge. Environmental concentration around morphological evolution suggest that rate-controlling process is and/or grain boundary diffusion atoms across zone.
