Graphene-carbon nanotube multi-stack three-dimensional architectures (graphene-CNT stacks) are formed by a “popcorn-like” growth method, in which carbon nanotubes are grown throughout the architecture in a continuous step. Alternating layers of graphene and a transition metal are grown by a vapor deposition process. The metal is fragmented and etched to form an array of catalytic sites. Carbon nanotubes grow from the catalytic sites in a vapor-solid-liquid process. The graphene-CNT stacks have applications in electrical energy storage devices, such as supercapacitors and batteries. The directly grown carbon nanotube array between graphene layers provides ease of ion diffusion and electron transfer, in addition to being an active material, spacer and electron pathway.

The invention belongs to the technical field of laser Raman detection, and discloses a surface-enhanced Raman scattering(SERS) substrate and a preparation method and an application of the surface-enhanced Raman scattering substrate. The surface of the substrate is coated by an ordered etched silver nanowire film, and the ordered etched silver nanowire film is formed by ordered arrangement of mutually-parallel etched silver nanowires, the average distance between adjacent etched silver nanowires is 0-15nm, and the surface roughness of one single etched silver nanowire is 0-20nm. The preparation method is as follows: etching is performed on silver nanowire surfaces by adopting a chemical method, the etched silver nanowires are self assembled by a three-phase interface method, and then the etched silver nanowires after self assembling are transferred to the surface of the substrate. The preparation method has the advantages of simplicity, low costs, easy realization and the like. If the substrate is used for SERS detection, the substrate has high detection sensitivity, and when Rhodamine B is used as a probe molecule, the lowest detection limit can reach 10-11M, and therefore the surface-enhanced Raman scattering substrate has an extensive potential application prospect in the fields of foods, environments, medical treatments, biology and the like.

Damascene templates have two-dimensionally patterned raised metal features disposed on an underlying conductive layer extending across a substrate. The templates are topographically flat overall, and the patterned conductive features establish micron-scale and nanometer-scale patterns for the assembly of nanoelements into nanoscale circuits and sensors. The templates are made using microfabrication techniques together with chemical mechanical polishing. These templates are compatible with various directed assembly techniques, including electrophoresis, and offer essentially 100% efficient assembly and transfer of nanoelements in a continuous operation cycle. The templates can be repeatedly used for transfer of patterned nanoelements thousands of times with minimal or no damage, and the transfer process involves no intermediate processes between cycles. The assembly and transfer processes employed are carried out at room temperature and pressure and are thus amenable to low cost, high-rate device production.
