What is a Silicon Carbide Semiconductor | Wolfspeed
Engineers frequently turn to silicon carbide semiconductors for their projects — but what is silicon carbide and what makes it unique? Semiconductors are special materials whose electrical conductivity lies somewhere between what you would see with a conductor (such as copper wire) and what you would see with an insulator (a ceramic-like glass).
