Is there a specific method to set a Mach Zehnder interferometer for surface relief grating inscription on polymer thin films?

Hello, I have built a Mach-Zhender interferomer in order to irradiate thin films of polymer (PMMA) with an interference pattern. These polymer thin films are doped with metallic precursors, and...

Could someone explain the mechanism of photo-induced reduction of metallic salt in a polymer solution or a polymer thin film?

I'm currently studying the in-situ formation of nanoparticles in metal salt doped polymer thin films by UV or visible laser irradiation + annealing. In this synthesis, the first step is to...

Could someone tell me approximately what are the right concentration and speed to fabricate PMMA film ranging form 1 to 5 microns by spin-coating?

I'm trying to spin-coat PMMA solutions (doped or not with various amount of gold salt) on glass substrates (1,5 cm^2). The PMMA was used as received (Aldrich, Mw=150000 by GPC) and dissolve in...
