Might anyone know of commercial sources for thin (and preferably single
crystal) FREESTANDING (i.e., unsupported by a substrate)
metal films, say 1000 A to a few microns?  

I have been told someone at the University of Denmark (?) routinely
produces high quality thin metal films, but I don't know the details
or whether anyone else produces these as well.

Many thanks!

Free standing foils (polycrystalline) are routine in the nuclear and
high energy atomic collision physics community -- you buy films deposited
on glass slides, float them off onto the surface of water, and then pick them
up (VERY carefully, especially if only 200 A) onto a holder.  Talk to 
your nearest accelerator jockeys for the latest info about sources.

As far as single crystal films, they do exist -- I have been on experiments
using them (years ago), but I have no idea where the best sources are.
I would expect if you found out typical sources of the polycrystalline films
the suppliers would know who does the single crystal foils.
