Types of Crystals | Chemistry [Master] - Lumen Learning
Structurally, silicon carbide is very complex; at least 70 crystalline forms have been identified. Its extreme hardness and ease of synthesis have led to a diversity of appliions — in cutting tools and abrasives, high-temperature semiconductors and other high-temperature appliions, the manufacturing of specialty steels and jewelry, and many more.

Semiconductor device - Wikipedia
A semiconductor diode is a device typically made from a single p–n junction. At the junction of a p-type and an n-type semiconductor there forms a depletion region where current conduction is inhibited by the lack of mobile charge carriers. When the device is forward biased (connected with the p-side at higher electric potential than the n-side), this depletion region is diminished, allowing
