World’s smallest superconductor found, and it’s less than 1nm wide

Scientists at the University of Ohio have discovered what they claim to be the world’s smallest superconductor, which is less than 1nm in width. The superconductor works on a molecular scale and is formed by four pairs of molecules. The research was published in Nature’s Nanotechnology paper, and has been called a path-breaking idea in the field of nanoscale electronics.In the past, interconnects of the modern chip fabrication process have always had problems with Joule heating and melting, as they traditionally have been built by metal, which conducts heat equally well as electricity. Interconnects on the nanoscale are called nanowires, whose electrical resistance unfortunately increases as they are made smaller. The 4 molecule chain that is the world's smallest...
