Homework Statement
I need to calculate n, k and d of an "unknown" thin film.
I have the transmission spectra of the substrate (MgF2) and substrate + "unknown" thin film
See the attachments with: three files
- two screenshots of the transmission spectra (see file name for description)
- one .txt file with divided values (can be plotted to see the T spectrum of the "unknown" thin film).
The Attempt at a Solution
If think very clear, I need to divide values of %T of substrate+thin film at values of %T of substrate, and I obtain transmission values/spectrum of thin film. After that I apply the equations from Swanepoel, 1983. It's correct?
Also, I want to know if it's possible to have the %T ~100 of the thin film. I think it is an oxide (MgO/ZrO). And I'm confusing to assign the Ts to %100; I said that because when I import the spectrum in PARAV 2.0, the software put the Ts value at %95.42, why?!
Please help me, I have backgrounds in Geology not in Physics (but I do my best), and It's very hard to understand without any help/advice.
