World’s smallest diamonds make tiny wires

Scientists at Stanford University, Menlo Park, Calif., and the Department of Energy’s SLAC National Accelerator Laboratory discovered a way to use diamondoids—the smallest possible bits of diamond—to assemble atoms into the thinnest possible electrical wires, just three atoms wide.
