Abstract: | A successful experimental synthesis of pure crystalline β- and α-C3N4 films on Si(100) substrate was carried out by bias-assisted hot filament chemical vapor deposition (bias-HFCVD). It is found that a mixed-phase C3-I-SixNy buffer layer was formed between the Si substrate and the C-N film. A “lattice match selection” was proposed to study the growth mechanism of C3N4 clusters composed of many crystal columns with hexagonal facets.
