Polytype stability is very important for high quality SiC single crystal growth. However, the growth conditions for the 4H, 6H and 15R polytypes are similar, and the mechanism of polytype stability is not clear. The kinetics aspects, such as surface-step nucleation, are important. The kinetic Monte Carlo method is a common tool to study surface kinetics in crystal growth. However, the present

Smart-cut layer transfer of single-crystal SiC using spin …
3/7/2012· The authors demonstrate “smart-cut”-type layer transfer of single-crystal silicon carbide (SiC) by using spin-on-glass (SoG) as an adhesion layer. Using SoG as an adhesion layer is desirable because it can planarize the surface, facilitate an initial low temperature bond, and withstand the thermal stresses at high temperature where layer splitting occurs (800–900 C).

Are you SiC of Silicon? Silicon carbide package technology
All SiC MOSFETs suffer from poor mobility in the channel (about 15-30X worse than silicon), but trench MOSFETs are better due to the crystal orientation of the channel. The trench JFET has a bulk channel with a much higher mobility, leading to the lower resistance per unit area in 650V-1700V rated devices.
