2014/11/10· Silicon and silicon carbide have also the same native insulating oxide that might be exploited for the processing and fabriion of Si-SiC-based electronic devices. The silicon lattice constant is 5.43 Å, while in 3C-SiC it is 4.36 Å, which results in a lattice mismatch of approximately 20% and it can lead to a highly defective epitaxial film, which can be detrimental for electronic devices.
Silicon carbide is a non-oxide engineering ceramic. It can have a moderately high thermal conductivity among the non-oxide engineering ceramics in the database. The properties of silicon carbide include five common variations. This page shows summary ranges
