Bringing silicon carbide to the masses - News

When 3C-SiC is grown on a silicon (111) substrate, this produces the ideal template for hexagonal GaN, due to a lattice mismatch of approximately 3.5 percent at the SiC-silicon interface. Reducing mismatch between GaN and silicon is valued highly, because it holds the key to reducing the intrinsic defects found in GaN when this material is grown on highly mismatch substrates, such as silicon

Superconductivity in heavily boron-doped silicon carbide

2009/1/28· 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.
