What is Silicon Carbide (SiC)?
Silicon Carbide is a wide-bandgap semiconductor known for:
- High thermal conductivity
- High breakdown voltage
- Radiation resistance
- Operation at high temperatures and high frequencies
These properties make SiC a leading choice for:
- Power MOSFETs & Schottky diodes
- High-temperature sensors
- Power conversion systems
- EV, aerospace & industrial electronics
- RF, 5G and photonics devices
Common Research Uses of SiC Wafers
Power Electronics
Used in high-efficiency power devices requiring low switching losses and high temperature tolerance.
High-Temperature & Harsh-Environment Sensors
SiC withstands heat, oxidation, and radiation—ideal for aerospace and automotive monitoring.
Optoelectronics & Photonics
4H-SiC substrates support UV, visible, and advanced photonics research.
Quantum Research
Semi-insulating SiC is used for color centers, defect engineering, and quantum photonic applications.
