Using a micro-focused high-energy X-ray beam, we have performed in situ time-resolved depth profiling during the electrochemical deposition of Sn into an ordered porous anodic alumina template. Combined with micro-diffraction are able to follow variation structure at atomic scale as function and time. We show that initially deposits bottom pores, forms metallic nanopillars preferred [100] orientation relatively low mosaicity. The lattice strain is found differ from previous ex measurements where had been removed support. dendritic nature pore affects growth mode results grain size, Such information nano-templated materials electrodeposition may improve future fabrication devices.
