- 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.
