SiC material properties - ScienceDirect

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).
