Study on the Influence of Plane Strain on Optical Properties of InP Materials through First-Principles Calculations

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