                                      Silicon Carbide (SiC) has emerged as one of the most important semiconductor materials for next-generation power electronics. Thanks to its wide bandgap, high thermal conductivity, and superior breakdown electric field, SiC devices offer significant advantages over traditional silicon-based technologies in electric vehicles, renewable energy systems, industrial drives, and high-voltage power conversion.
