Content:
Contrary to the formation of complicated polycrystals induced by general crystallization, a modulated
superlatticelike nanostructure, which grows layer by layer from the surface to the interior of a
Pd40Ni10Cu30P20 metallic glass, is observed via isothermal annealing below the glass transition temperature.
The generation of the modulated nanostructure can be solely controlled by the annealing temperature,
and it can be understood based on the fast dynamic and liquidlike behavior of the glass surface.
The observations have implications for understanding the glassy surface dynamics and pave a way for the
controllable fabrication of a unique and sophisticated nanostructure on a glass surface to realize the
properties’ modification.
