Abstract
This research scrutinizes the impact of plane strain on the optical characteristics of Indium Phosphide (InP) employing first-principles methodology, grounded on the Density Functional Theory (DFT). The findings suggest that the peaks of the spectral response curves of the dielectric function, refractive index, extinction coefficient, optical absorption coefficient, and reflection coefficient of InP, when subjected to plane tension strain, shift towards lower energy of electromagnetic wave frequency in the horizontal coordinate. Concurrently, static quantities such as the dielectric coefficient, refractive coefficient, and reflection coefficient of InP demonstrate an upward trend with an increase in the plane tension strain. Intriguingly, the influence of compressive strain on the photoelectric response of InP manifests contrary behavior to that of the tensile strain.
