Schematic of a diffusion dominant deformation model for the nanoligament.
(a)–(b) Without tensile stress curvature driven diffusion flow will smooth out the necked area in the ligament leaving a ligament with more uniformed cross section (b). (c)–(d) Tensile stress increased the chemical potential in the thinnest part to overcome the chemical potential gradient caused by curvature. The two boundaries are sinks to the atom flow. (e)–(f) Sample profile evolution after fracture.
