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.

N Type,N Type SiC,N Type Semiconductor - Silicon carbide

When a doped semiconductor contains excess holes it is called "p-type", and when it contains excess free electrons it is known as "n-type". The semiconductor material used in devices is doped under highly controlled conditions to precisely control the loion and concentration of p- and n-type dopants.

Increasing carrier lifetimes for high-voltage silicon carbide

Increasing carrier lifetimes for high-voltage silicon carbide Researchers in Japan have been developing ways to increase minority carrier lifetimes in lightly doped silicon carbide (SiC) with a view to insulated-gate bipolar transistors (IGBTs) [Tetsuya Miyazawa et al, J. Appl. Phys., vol118, p085702, 2015].

In this paper, we study the electrochemical anodization of n-type heavily doped 4 H-SiC wafers in a HF-based electrolyte without any UV light assistance. We present, in particular, the differences observed between the etching of Si and C faces. In the case of the Si face, the resulting material is mesoporous (diameters in the range of 5 to 50 nm) with an increase of the ‘chevron shaped
