nanowires was analyzed via EDS and XRD characterizations, which identified a
main phase constitution of cupric oxide. Serving as a transitional bridge, the relatively larger scale gratings connect the oxide nanowires with the underneath metal
substrates and also play the role of skeleton which supports the integrated surface
architectures. Resembling the grass taking root in the soil, the oxide nanowires
are tightly connected with the skeleton resulting from the in situ growing process.
The precursor structures and the nanowires are naturally combined without obvious
interface characteristics, making the constructed architectures an intact and robust
structural system.
With different types of precursor structures introduced by ultrafast laser, the microscopic environment for growing oxide nanowires also differs. As an illustration, we
have intentionally fabricated two kinds of 1D periodic structures through adapting the
ultrafast laser structuring process, as shown in Fig. 2.13. Despite that the two grating
