SIMS imaging of lithium-ion migration within a solid electrolyte specimen. Grain boundaries resistant to ionic diffusion have created an uneven 6 Li distribution. Quantitative analysis found that ...
Twin defects introduced into copper grains cause the slowing of atomic migration along the grain boundary under current-induced conditions. In polycrystalline solids, the grain boundary regions are ...
