Abstract
In the paper titled above [Najim et al. in J. Mater. Sci.: Mater. Electron., 2022], there is a fatal scientific error, as the authors claim that they used the envelope method in the calculation of the film thickness and the refractive index while we find that the transmittance curves (See Fig. 5 in [Najim et al. in J. Mater. Sci.: Mater. Electron., 2022]) are smooth and free from any interference fringes (maxima (TM) or minima (Tm)), how was that done? Where are the TM and Tm values? How do the authors use Eqs. 4–6 in their paper [Najim et al. in J. Mater. Sci.: Mater. Electron., 2022]?
