Detail Application of Silicon Carbide

Because of SiC physical and electronic properties,silicon carbide based device are well suitable for short wavelength optoelectronic, high temperature, radiation resistant, and high-power/high-frequency electronic devices,compared with Si and GaAs based device.
Many researchers know the general SiC application:III-V Nitride Deposition;Optoelectronic Devices;High Power Devices;High Temperature Devices;High Frequency Power Devices.But few people knows detail applications, here we list some detail application and make some explanations:
1. SiC substrate for X-ray monochromators:such as,using SiC's large d-spacing of about 15 A;
2. SiC substrate for high voltage devices;
3. SiC substrate for diamond film growth by microwave plasma-enhanced chemical vapor deposition;
4. For silicon carbide p-n diode;
5. SiC substrate for optical window: such as for very short (< 100 fs) and intense (> 100 GW/cm2) laser pulses with a wavelength of 1300 nm. It should have a low absorption coefficient and a low two photon absorption coefficient for 1300 nm.
6. SiC substrate for heat spreader: For example,the Silicon carbide crystal will be capillary bonded on a flat gain chip surface of VECSEL (Laser) to remove the generated pump heat. Therefore, the following properties are important:
1) Semi-insulating type required to prevent free carrier absorption of the laser light;
2) Double side polished are preferred;
3) Surface roughness: < 2nm, so that the surface is enough flat for bonding;
7. SiC substrate for THz system application: Normally it require THz transparency
8. SiC substrate for epitaxial graphene on SiC:Graphene epitaxy on off axis substrate and on axis are both available, surface side on C-face or Si face are both available.
9. SiC substrate for process development loke ginding, dicing and etc
10. SiC substrate for fast photo-electric switch
11. SiC substrate for heat sink: thermal conductivity and thermal expansion are concerned.
12. SiC substrate for laser: optical, surface and stranparence are concerned.
13. SiC substrate for III-V epitaxy, normally off axis substrate are required.
