Real-Time Observation of Impurity Diffusion in Silicon Nanowires

Solid-state diffusion of the transition metal impurities, gold (Au), nickel (Ni), and copper (Cu), in silicon (Si) nanowires was studied by in situ transmission electron microscopy. Compared to diffusion in a bulk crystal, Au diffusion is extremely slow when the amount of metal is limited but signif...
