2019/1/1· In SiC, the valence electrons are slightly localized near C atoms, due to a higher electronegativity of carbon than that of silicon (C: 2.5, Si: 1.8). This ionicity gives this material polarity, which induces different electronic and chemical properties on different faces (e.g., Si face vs C face).
Electrons in SiC need about three times as much energy as they do in silicon to become excited enough to reach their conductive state. This factor, the material’s high electron mobility and its eight-fold higher electrical breakdown field allow SiC components to switch at higher frequencies, operate reliably at temperatures as high as 650 degrees Celsius and handle voltages up to 10 times
