炭化ケイ素の導電性
Okamoto et al. measured the conductivity of silicon carbide at various temperatures and found that small amounts of Si additive did not increase conductivity by two to three orders of magnitude, but exceeding 5 mol% caused conductivity levels to soar by up to three orders of magnitude. Silicon carbide is a semiconductor material, capable of being altered into either an n-type or p-type state by doping with aluminium, boron, gallium, phosphorus or nitrogen ions. Electrical Conductivity Silicon carbide is a semiconductor material, meaning that it lies somewhere between metals (which conduct electricity) and insulators (which resist current). At lower temperatures, silicon carbide behaves more like an insulator by resisting electrical […]
