Carbure de silicium — Wikipédia

Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.

Scanning transmission electron microscopy (STEM) was used to examine sintered and hot-pressed aluminium-doped silicon carbide. Grain-boundary segregation of Al was observed in both materials. Semi-quantitative analysis was carried out on the Al-saturated hot-pressed material. An estimated heat of segregation between 116 and 174 kJ mol−1 was calculated from the STEM data and equilibrium

The 3 × 3 × 1 supercell model of 4H–SiC with 72 atoms was shown in Figure 1.The large supercells used in the calculations allow us to simulate the distribution of various dopants and their magnetic configurations. As shown in Figure 1, the Cr dopant is fixed at the position marked 0, the Si atom labeled 1-12 is the position substituted by the doped Co atom, and the silicon vacancy is

AlGaN Interlayer

Improved structural quality and tensile stress releasing are realized in unintentionally doped GaN thin films grown on 6H–SiC substrates by metal organic chemical vapor deposition. Using the optimized AlGaN interlayer, we find that the full width at half maximum of x-ray diffraction peaks for GaN decreases dramatically, indiing an improved crystalline quality.
