Polytype Distribution in Circumstellar Silicon Carbide | …

The inferred crystallographic class of circumstellar silicon carbide based on astronomical infrared spectra is controversial. We have directly determined the polytype distribution of circumstellar SiC from transmission electron microscopy of presolar silicon carbide from the Murchison carbonaceous meteorite. Only two polytypes (of a possible several hundred) were observed: cubic 3C and

On the correlation between the carbon content and the …

Thermal oxides on p-type silicon carbide exhibit high densities of interface states and fixed charge. Understanding the effect of the oxide composition on the electrical properties is imperative to improve the quality of oxides on p-type silicon carbide. In this work, we use angle resolved x-ray photoelectron spectroscopy to profile the oxide composition. The result is a direct correlation

Electric vehicles: Considering silicon carbide over silicon …

Until recently, silicon carbide (SiC) has not been extensively tapped for use as a semiconductor, compared to nearly ubiquitous silicon (Si) and gallium arsenide (GaAs) semiconductors. Optimized to harness or limit stray inductance, SiC semiconductors offer several advantages in power electronics.

Characteristics of 6H-silicon carbide PIN diodes …

Silicon carbide PIN diodes have been fabried using a direct-write laser-doping technique that reduces defect generation compared to the conventional ion-implantation technique. Nitrogen and aluminum were successfully incorporated into SiC as n-type and p-type dopants, respectively. Rutherford backstering studies were conducted to compare the lattice defect generation by the laser-doping
