Tin deposition

Tin can be deposited by e-beam evaporation. It was evaporated in the Alcatel e-beam evaporator, which is being decommissioned, but has not yet been evaporated in the Physimeca or the Temescal, which we have now (August 2018). Please contact the Thin Film group if you would like to deposit tin.

	E-beam evaporation (Temescal)

Comment	Tin has not yet been deposited in the Temescal to date (August 2018). Please contact the Thin Film group if you would like us to develop the process.
