After the pioneering investigations into graphene-based electronics at Georgia Tech, great strides have been made developing epitaxial graphene on silicon carbide (EG) as a new electronic material. EG has not only demonstrated its potential for large scale appliions, it also has become an important material for fundamental two-dimensional electron gas physics. It was long known that
Is Silicon a Metal or Nonmetal? - Reference
2020/3/25· Silicon is a metalloid, which means it is a type of metal but has some nonmetal qualities depending on what element it is reacting with. An example of this would be the fact that silicon is not a good conductor of electricity.
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.”

Deoxidization - Wikipedia
Deoxidization is a method used in metallurgy to remove the oxygen content during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food. Deoxidation is important in the steelmaking process as oxygen is often detrimental to the quality of steel produced.
