Ge-evaporation

[Petra Reinke]

Dear All,

we want to evaporate Ge from an Omicron EFM 3 electron beam evaporator with a W-crucible. Unfortunately we do not have a QCM on this chamber and are for geometric reasons unable to mount one for the measurement of rates. Have any of you the power-deposition rate relation for Ge evaporations? Or a few hints as to the evaporation conditions for at least a few rates? 

kind regards, Petra

Petra,

When I start to evaporate a new material, I find it useful to look up the vapour pressure tables to give me an idea of the temperature I need for a reasonable evaporation time. Kurt Lesker provides a very useful table for purpose. Ge is at http://www.lesker.com/newweb/deposition_materials/MaterialDeposition2.cfm?pgid=0
