SiC Crystal Structure

 

SiC Crystal has many different crystal structures,which is called polytypes.The most common polytypes of SiC presently being developed for electronics are the cubic 3C-SiC, the hexagonal 4H-SiC and 6H-SiC, and the rhombohedral 15R-SiC. These polytypes are characterized by the stacking sequence of the biatom layers of the SiC structure.For more details, please enquire our engineer team.

SiC MicroElectromechanical Systems (MEMS) and Sensors

 

As described in Hesketh’s chapter on micromachining in this book, the development and use of siliconbased MEMS continues to expand. While the previous sections of this chapter have centered on the use of SiC for traditional semiconductor electronic devices, SiC is also expected to play a significant role in emerging MEMS applications . SiC has excellent mechanical properties that address some shortcomings of silicon-based MEMS such as extreme hardness and low friction reducing mechanical wear-out as well as excellent chemical inertness to corrosive atmospheres. For example, SiCs excellent durability is being examined as enabling for long-duration operation of electric micromotors and micro jet-engine power generation sources where the mechanical properties of silicon appear to be insufficient .
