[labnetwork] Zinc Selenide (ZnSe) deposition

[Youry Borisenkov]

Happy Friday FabNetwork,
We have a user who is looking to deposit 700-1000 nm ZnSe on Calcium
fluoride (CaF2) substrate.
Do any of you provide such service?

Here are more details:
The substrate is CaF2 (22mmx22mmx0.17mm). One important consideration is
that the substrates are quite brittle, so the mounting procedure would need
to be gentle.
>From what I've read, evaporation will also work - RF sputtering and thermal
evaporation appear to be the most common methods for deposition. e-beam
deposition is also sometimes used.
The thickness of the ZnSe layers should be around 700-1000nm.
I would be looking to do deposition both directly onto the coverglass, as
well as onto a polymer layer - The final structure in order of layers will
be CaF2/Au( or ITO)/ZnSe/P3HT Polymer/PMMA/ZnSe/Au( or ITO)
