Covalent superconductor

Parts of a high pressure cell after the synthesis of heavily boron doped superconducting diamond. The diamond (black ball) is located between two graphite heaters

Covalent superconductors are superconducting materials where the atoms are linked by covalent bonds. The first such material was boron-doped synthetic diamond grown by the high-pressure high-temperature (HPHT) method. The discovery had no practical importance, but surprised most scientists as superconductivity had not been observed in covalent semiconductors, including diamond and silicon.
