Menlo Park, Calif. -- A study at the Department of Energy's SLAC National Accelerator Laboratory suggests for the first time how scientists might deliberately engineer superconductors that work at higher temperatures.
In their report, a team led by SLAC and Stanford University researchers explains why a thin layer of iron selenide superconducts -- carries electricity with 100 percent efficiency -- at much higher temperatures when placed atop another material, which is called STO for its main ingredients strontium, titanium and oxygen.
