In this paper, We examined the optical properties of prescribed materials, such as the refractive index n(ω), dielectric constant and absorption coefficient α(ω), of zinc-blende (ZB) and InN semiconductor using the plane-wave pseudo-potential method within density functional theory (DFT) at pressures of 0 GPa, 10 GPa, 20 GPa, and 30 GPa. We found a reasonable agreement between the computed values of these parameters and the experimental data and those published by other studies. In our study, we explore the theoretical optical properties of indium nitride (InN).The first-principle calculations for the InN in zink-blende structure have been performed with LDA exchange-correlations functional. This material is of great interest due to their properties important to both applications in optoelectronics and to fundamental material science.

摘要

In this paper, We examined the optical properties of prescribed materials, such as the refractive index n(ω), dielectric constant and absorption coefficient α(ω), of zinc-blende (ZB) and InN semiconductor using the plane-wave pseudo-potential method within density functional theory (DFT) at pressures of 0 GPa, 10 GPa, 20 GPa, and 30 GPa. We found a reasonable agreement between the computed values of these parameters and the experimental data and those published by other studies. In our study, we explore the theoretical optical properties of indium nitride (InN).The first-principle calculations for the InN in zink-blende structure have been performed with LDA exchange-correlations functional. This material is of great interest due to their properties important to both applications in optoelectronics and to fundamental material science.
