Abstract

A quantum model for optical conductivity that treats light as a particle is presented. Based on this assumption, the optical characteristics of the material are calculated and compared to experimental findings. The band gap energy of a material changes with frequency and refractive index. We provided an equation of the line extrapolated in the Tauc plot. The obtained formula for optical conductivity reveals that the band tailing parameter in the Tauc formula is dependent on the speed of light, the Planck constant, and the material's refractive index. The determination of this constant helps establish the value of the band. The values of this constant are found to be consistent with various experimental results. Two electric conductivities distinguishing Abraham and Minkoswi's light momentum relationship inside materials are proposed.

光导率和尾迹参数的验证

本文提出了一种将光视为粒子的光导量子模型。根据这一假设，计算了材料的光学特性，并与实验结果进行了比较。材料的带隙能随频率和折射率的变化而变化。我们提供了陶克图中外推线的方程。所获得的光导率公式表明，陶氏公式中的带尾参数取决于光速、普朗克常数和材料的折射率。该常数的确定有助于确定带值。该常数的值与各种实验结果一致。提出了区分材料内部亚伯拉罕和明科斯维光动量关系的两种电导率。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
