DETERMINATION OF THE OPTICAL CONSTANTS OF THIN FILMS FROM OPTICAL TRANSMISSION DATA

Optical constants and thickness of thin films of ZnO, SnO and A_2 O_3 are obtained by fitting of transmittance data to model equations. The Swanepoel transmission equation was used as the custom equation in the MATLAB Software. Six constants are determined using the curve fitting toolbox in MATLAB application. The Cauchy dispersion equation was used to determine the refractive index, the refractive index of ZnO, SnO and A_2 O_3 are 2.096, 2.000 and 2.046 at 600nm and the extinction coefficients of 0.1056, 0.066256 and 0.143478 respectively. The accuracy of the optical constants and thickness was very accurate compared with those obtained from other methods. Optical constants and thickness can be obtained with high accuracy by fitting transmittance data.

PRISA: a user-friendly software for determining refractive index, extinction co-efficient, dispersion energy, band gap, and thickness of semiconductor and dielectric thin films

Nano Express, 2021

A user-friendly software PRISA has been developed to determine optical constants (refractive index and extinction co-efficient), dispersion parameters (oscillator energy and dispersion energy), absorption co-efficient, band gap and thickness of semiconductor and dielectric thin films from measured transmission spectrum, only. The thickness, refractive index, and extinction co-efficient of the films have been derived using Envelope method proposed by Swanepoel. The absorption co-efficient in the strong absorption region is calculated using the method proposed by Connel and Lewis. Subsequently, both direct and indirect bandgap of the films is estimated from the absorption co-efficient spectrum using Tauc plot. The software codes are written in Python and the graphical user interface is programmed with tkinter package of Python. It provides convenient input and output of the measured and derived data. The software has a feature to cross check the results by retrieving transmission spec...
