Coaxial Metal Nano‐/Microcables with Isolating Sheath: Synthetic Methodology and Their Application as Interconnects

Abstract Synthesis of coaxial nano‐/microcables has been an intensive research subject due to their heterogeneous structures, tuneable properties, and important applications in nano‐/micrometer‐scale electronic and optoelectronic devices. Research on the fabrication of nanocables via solution strategies has made great progress in the past few years. In this Research News article, rapidly emerging new solution strategies such as hydrothermal carbonization (HTC) and synergistic soft–hard templates (SSHTs) are highlighted. Unique and flexible coaxial nano‐/microcables synthesized by those methods have obvious advantages such as long‐term stability and their electrical transport properties, compared with bare counterparts, suggesting that they are potential candidates as interconnects in the future.
