Original Abstract

The absorption coefficient is an important optical property in characterizing semiconducting materials. It plays a significant role in studying optical characteristics, electrical structure, energy band structure, and the creation/annihilation of excitons when a semiconducting material absorbs electromagnetic radiation. In this study, an enhanced theoretical model will be introduced and applied to characterize thin films prepared from UPR4 (unsaturated polyester resin) single-component epoxy resin, which is important to study the charge flow at the interface of tungsten-UPR4 composite field emission cathodes

Keywords

absorption coefficient, energy gap, Urbach tailing energy, Tauc plot, transmittance, and reflectance.
