Processing induced extended defects in silicon carbide - …

Although SiC has shown potential for use as a semiconductor material, there are still processing issues and related defects that prevent the realization of many devices. Three defect types primarily associated with the SiC basal planes have been examined; these are hexagonal voids, doping related stacking faults, and polytype transformation of 3C epitaxial layers at elevated temperatures

NSM Archive - Silicon Carbide (SiC) - Band structure

More than 200 different polytypes of SiC are known. However, about 95% of all publiions deal with three main polytypes: 3C, 4H, and 6H. In all main polytypes of SiC, some atoms have been observed in association both with cubic (C), with hexagonal (H) and with

The elastic constants of silicon carbide: A Brillouin …

The complete sets of elastic constants of 4H and 6H silicon carbide single crystals were determined by Brillouin stering. The elastic constants of 6H SiC are C11=501±4, C33=553±4, C44=163±4, C12=111±5, and C13=52±9 GPa; the corresponding ones of 4H SiC are the same within experimental uncertainties. The compressibility, 4.5×10−3 GPa, is about 3–5 times smaller than those reported

10/11/2014· 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.
