Silicon Carbide: a Love-Hate Relationship | EE Times
Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
