Laser assisted welding of layered metallic nanostructure

We present laser assisted welding of the layered metallic nanostructure, including two gold NWs and insulating layers, to reveal a prominent approach to interconnect the nanostructures in different layers. Since these nanostructures are building blocks for plasmonic integrated circuits, this work provides a promising and simple technology for the development of nanowire-related plasmonic or electric interconnect.
