Direct observation of blocked nanoscale surface evaporation on SiO2 nanodroplets

(author unknown)



Neng Wan, Jun Xu, and Li-Tao Sun et al.

Nano-scale surface evaporation of SiO2 nanodroplets from a volcano-shaped tip (tip diameter d ∼ 20 nm to 70 nm) was observed directly using an in situ transmission electron microscopy method. Au nanoparticles, those precipitated in the SiO2 matrix after an Au catalyzed growth, diffused and pinned ... [Appl. Phys. Lett. 101, 183114 (2012)] published Fri Nov 02, 2012.
