Navarro SiC - Silicon Carbide
Silicon carbide develops in the furnace as a solid cylindrical ingot around the graphite core, with concentric layers that decrease their SiC content with the distance from the core. It can be black or green depending on the composition of the raw materials used.

On the Evaluation of Gate Dielectrics for 4H-SiC Based …
AlN and Al 2 O 3 are two promising compatible (almost similar dielectric constant with 4H-SiC) candidates as gate dielectric with 4H-SiC materials. However, lower bandgap of AlN (6.2 eV) in comparison with Al 2 O 3 (8.7 eV) or SiO 2 (8.9 eV) might be disappointing for 4H-SiC devices, but a lattice mismatch to SiC of only 1% along with almost the same thermal expansion coefficient of up to …

Relative Permittivity - the Dielectric Constant
The dielectric constant - also called the relative permittivity indies how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum".
