The 2D janus hybrid (gold NPs/graphene) superstructures were built via a rapid, solventless sputtering method in 10 seconds. The size and morphology of gold NPs can be fine controlled by adjusting the sputtering current and time. The resulting graphene hybrids also enjoyed tunable area density and desirable thermal stability.
Silicon nanostructures were fabricated by a natural lithography technique, with sizes far beyond the limit of conventional, by a self-organizing gold colloidal particle monolayer as an etch mask. The silicon nanostructures with high density and uniformity in height and shape were obtained using reactive ion etching (RIE). The uniform spatial distribution of the Si nanostructures can also be obtained...
