Optical Properties of Defective Silicon Carbide Nanotubes: Theoretical Study
The optical properties of silicon carbide nanotubes with different orientations of Stone Wales defects were investigated for polarized light, unpolarized light and light incident through polycrystalline media. Density functional theory were used to study the effect of different orientations of Stone Wales defects on the optical properties of chiral (8, 4) silicon carbide nanotube. We monitored the corresponding changes in dielectric function, optical conductivity, absorption, reflection spectra, refractive index, and loss function. We found that introducing different orientations of Stone Wales defects to silicon carbide structure modified yet improved the optical properties of the nanotubes.
