(600b) 3-D Electrically Interconnected Nanowire Networks Formed By Fluidic Diffusion Bonding

We demonstrate a new strategy to bond and integrate nanowires (NWs) using fluidic interfacial diffusion bonding of gold (Au). The strategy was used to form very large scale, electrically interconnected three dimensional (3D) NW networks composed of both homogeneous and heterogeneous (multisegmented) NWs. The size of the networks ranged from tens micrometers to millimeters. We have measured the electrical characteristics of the networks and explored one application of the networks in 3D spatial chemical sensing.
