Crystalline silicon carbide (SiC) has structures of tetrahedrally coordinated lattice. The atomic layers can stack in cubic (C), hexagonal (H),or rhoohedral (R) configurations. These structures are labeled by the symmetry (C, H, or R) following the nuer of the layers in one period of the stacking sequence.

P-n mesa diodes fabried with positive angle beveling and oxide passivation can withstand temperatures of up to 300–400 °C in the breakdown regime. Uniform avalanche breakdown in 4H silicon carbide appears to have a positive temperature coefficient, in contrast to the 6H polytype, where the temperature coefficient is negative.
