Hi every body!
To those who use the Software S.E.A.from the Sopra Firm , to perform fits of their experimental data collected from a spectroscopic ellipsometer. Can you help me about Tauc Lorentz fit parameters? Give their definitions and In what range they must vary in order to have a good fit, of Tg(Psi) and Cos(Delta) for example? Thak you.
Hi Mohand,
I’m a user of WASE ellipsometer, but maybe information below can solve your problem:
In my publication:
https://www.researchgate.net/publication/267868470_Characterisation_of_coloured_TiOxTiglass_systems
I have been used T-L model to parameterize optical properties of TiOx film deposited on Ti thick layer.
In Fig.7 I present the example of the fit. In pages 4 and 5 I showed expressions and found parameters of Tauc-Lorentz oscillator with uncertainty.
