Fig. 1. Reverse current-voltage characteristics of a typical batch of 1 mm x 1 mm 6H-Sic pn diodes produced on the same wafer. The diodes fail at differing voltages well below the 6H-Sic avalanche breakdown field due to the presence of localized defects in the junctions. - "Performance Limiting Micropipe Defects in Silicon Carbide Wafers"
Growth and Characterization of Silicon Carbide Crystals | …
Over the past 20 years, considerable advances have been made in silicon carbide single-crystal growth technology through understanding of growth mechanisms and defect nucleation. Wafer sizes have been greatly improved from wafer diameters of a few millimeters to 100 mm, with overall disloion densities steadily reducing over the years.

SiC Magnetometer - NASA
Silicon Carbide is extremely robust and has the ability to operate in harsh planetary magnetic fields, sensing with quantum centers in SiC, which are fundamental physical constants in nature. Currently, our “off-the-shelf” sensor is characterized with sensitivity on the order of 100 nT Hz-1/2, as it was not designed in any way for magnetometry.

Silicon wafers of high purity (99.0% or higher) single-crystalline material can be obtained via a coination of liquid growth methods, such as pulling a seed crystal from the melt and by
Method of Preparing Low Defect Surfaces on Silicon …
Such growth schemes are very time-consuming, however, and have thus far prevented the commercialization of laser diodes based on GaN. For instance, the overall scheme for producing low defect density in GaN films is to first grow an aluminum nitride (AIN) film on a silicon carbide (SiC) substrate and then deposit a GaN film on top of the AIN film.

Bright-line defect formation in silicon carbide injection …
Irreversible formation of a network of linear defects has been observed for images showing recoination luminescence from injection diodes in hexagonal silicon carbide. The defects are related to disloions that are initially formed as a result of thermal stress near the tip of the contact probe and subsequently propagate through the diode area. The disloion network appears in the images

The usual graininess is due to the low mobility of aluminium atoms on the growth surface. The III-nitride material was grown on silicon-face 4H silicon carbide. Hot-wall metal-organic chemical vapor deposition (MOCVD) was used to create epitaxial structures with 60nm AlN nucleation, a 200nm GaN channel, an AlN interlayer of up to 1.5nm, a 10-14nm AlGaN barrier (~30% Al), and a 2nm GaN cap.
