Superconductivity in heavily boron-doped silicon carbide
28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.
