Band structure of silicon carbide - …

Using the linear augmented cylindrical wave method in the muffin-tin approximation, we have calculated the band structure of (n, n) and (n, 0) silicon carbide nanotubes for n = 5–10. In the range n = 7–10, (n, n) nanotubes are semiconductors, and their band gap decreases steadily with increasing n: 0.28 eV at n = 7, 0.26 eV at n = 8, 0.19 eV at n = 9, and 0.11 eV at n = 10.

Overview of Silicon Carbide - …

Silicon carbide is a material that presents strong polytypism. Numerous hexagonal (H) structures of SiC have been identified, in addition to the common cubic form, denoted as SiC(3C). The polytypes of SiC are semiconductors with varying band gap and they are natural superlattices [2]. The most common polytype in the hexagonal form is SiC(6H).
