The Earth’s core is supposed to contain light elements such as Si, O, and S based on the comparison of seismic observations with the equation of state of the core materials, and the phase relations of the iron –light element systems at high pressures and temperatures [2].
As the density of the reaction products is larger than the density of the mantle, so it is not possible to rise to more than a few hundred kilometers.The Unreacted mantle material and uneven reaction products ultimately constitute the layer [13].These unevenness of chemical composition and thermal nonuniformity in layer are one of the possible reasons resulted in the seismic velocity anomalies and lateral heterogeneity.

Furthermore, the ultra-high voltage rating in combination with huge current capability requires much large chip size, which is still a bottleneck for SiC material to achieve acceptable defect level and effective cost.
The device edge termination ultilizes the high critical electric field of SiC material to enable the device breakdown voltage being able to reach the ideal value of Si with good process windows in terms of interface charge, deep trench profile and 3C-SiC quality, etc., since the breakdown spot can be easily moved from the edge to the active cell.
Thanks to the high critical electric field of SiC material, the impact ionization rate in the new termination structure is reduced significantly, and its breakdown location is moved away from the oxide/semiconductor interface into silicon bulk.
