FAQ:
Q: What is the difference between 4H-SiC and SiC?
A: 4H-Silicon Carbide (4H-SiC) stands out as a superior polytype of SiC due to its wide bandgap, excellent thermal stability, and remarkable electrical and mechanical characteristics.
Q: When should SiC be used?
A: If you want to quote someone or something in your work, and you notice the source material contains a spelling or grammatical error, you use sic to denote the error by placing it right after the mistake.
Q: Why 4H SiC?
A: 4H-SiC is preferred over 6H-SiC for most electronics applications because it has a higher and more isotropic electron mobility than 6H-
