Date posted: 18/06/2012 Researchers at Rice University have created a tiny coaxial cable only 100 nanometers wide with higher capacitance than previously reported microcapacitors. The nanocable,produced with techniques pioneered in the nascent graphene research field, could be used to build next-generation energy-storage systems. It could also find use in wiring up components of lab-on-a-chip processors. The tiny coaxial cable is similar in makeup to the ones that carry cable television signals into millions of homes and offices. The heart of the cable is a solid copper wire that is surrounded by a thin sheath of insulating copper oxide. A third layer, another conductor, surrounds that. In the case of TV cables, the third layer is copper again, but in the nanocable it is a thin layer of carbon measuring just a few atoms thick. This three-layer, metal-insulator-metal structure can also be used to build energy-storage devices called capacitors.
