In situ atomic imaging of coalescence of Au nanoparticles on graphene: rotation and grain boundary migration

Abstract

Using in situ transmission electron microscopy, we demonstrated that gold nanoparticles are unified via “oriented attachment” assisted either by nanoparticle rotation or grain boundary migration at the attachment interface. We also observed that the combined nanoparticle changes shape with stable facet planes via surface diffusion, along with recrystallization.
