A study of the dependence of the electronic structure and energetic stability on the chemical surface passivation of cubic porous silicon carbide (pSiC) was performed using density functional theory (DFT) and the supercell technique. The pores were modeled by removing atoms in the  direction to produce a surface chemistry composed of only carbon atoms (C-phase). Changes in the electronic
SiC (silicon carbide) - GlobalSino
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.
