Tauc plot refined

The Tauc plot is a well-known method for determining the bandgap of amorphous and crystalline semiconductors, using the measured absorption coefficient. The common Tauc plot method remains a widely used and effective approach for estimating the bandgap of diverse materials, thus exhibiting that it is a versatile tool in studying material properties. When experimental misapplications, such as inappropriate spectral range selection, are properly addressed, an accuracy on the order of ±50 meV can be achieved. Furthermore, the refined Tauc plot methods, incorporating improved data preprocessing and fitting strategies, enable even greater precision in bandgap determination, alongside a larger set of extracted parameters.
