Silicium | Article about Silicium by The Free Dictionary

Silicon forms dark gray crystals with a metallic luster. The crystals have a face-centered cubic diamond-type lattice with the constant a = 5.431 Å and density 2.33 g/cm 3 . A new, apparently hexagonal, modifiion with the density of 2.55 g/cm3 has been obtained at very high pressures.

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.
