Description
Konstantin P. Shchukin and co-authors tune a fulleride superconductor directly on a chip by driving rubidium ions into a carbon film, in a 2026 paper. Older ways of adding alkali metals give poor control over the final composition, especially in thin films. An electric current pushed the ions in gradually while the sample sat in ultrahigh vacuum.
Raman spectroscopy tracked the composition during the process, and transport tests measured superconductivity. As the formula moved toward three rubidium atoms per sixty-carbon molecule, the transition temperature roughly doubled within the measured range. Smooth control by timing the current is the key advantage. The method suits battery research and other intercalated materials as well.
