Silicon Carbide Crystals - Brilliant Iridescence

Description. Silicon carbide is a rare but naturally occurring mineral found in microscopic crystals associated with some kierlites. Natural crystals are named moissanite and man made crystals, such as these, are commonly called carborundum. Carborundum is produced commercially for use in abrasives and other industrial appliions.

Crystals | Free Full-Text | Imprinting the Polytype …

Silicon carbide is a material with a multistable crystallographic structure, i.e., a polytypic material. Different polytypes exhibit different band gaps and electronic properties with nearly identical basal plane lattice constants, making them interesting for heterostructures without concentration gradients. The controlled formation of this heterostructure is still a challenge. The ability to
