WebThe EG's quality in GOS however remains mediocre due mostly to the high density of crystal defects in the 3C-SiC/Si films caused by the large (~ 20%) lattice-mismatch between Si and 3C-SiC crystals. Resultant Si out-diffusion along the planar defects during the higherature (~ 1525 K) graphitization annealing can also account for the degradation.Weband so heteroepitaxy has been performed on sapphire (mismatch of about 15 %) and silicon carbide (SiC, mismatch of about 3 %) [1]. It is expected that SiC with a smaller mismatch would lead to heteroepitaxial GaN of higher quality than sapphire, but several factors other than mismatch are
