Carbon Molecule With A Charge Could Be Tomorrow's Semiconductor

As part of the research to place gadolinium atoms inside the carbon cage of a fullerene molecule for MRI applications, researchers created an 80-atom carbon molecule with two yttrium ions inside. They then replaced one of the carbon atoms with an atom of nitrogen and discovered that the extra electron ducks inside between the yttrium ions, forming a one-electron bond with unique spin properties that can be altered.
