Synthesis and dynamics of PtSi nanoparticles on a carbon nanofilm by in-situ TEM Joule heating

In-situ transmission electron microscopy has evolved to be a unique technique to study process dynamics down to the atomic scale. Here, we show that in-situ Joule heating of carbon nanofilms facilitates the investigation of the nucleation, annealing, diffusion and evaporation of PtSi nanoparticles i...
