Fluid-like Surface Layer and Its Flow Characteristics in Glassy Nanotubes

31 Dec 2016 Wingert Matthew C. Kwon Soonshin Cai Shengqiang Chen Renkun

We observed strongly size-dependent viscoelasticity in amorphous SiO2 and Si nanotubes with shell thickness down to ~8 nm. A core-shell model shows that a ~1 nm thick fluid-like surface layer has a significant effect on the mechanical behavior of nanotubes and matches well with our experimental results... (read more)
