Does anyone have any good references on the construction of Effusion cells and RHEED/Electron guns. Is it better to use MOSi2 or Ta for the heating element in the Effusion cell?
Do the components in the cermaic crucible of the Effusion cell vaporize more readily due to the fact that a vacuum is pulled on the entire system?
From what I have read this is the most efficient method of depositing things like Ga As Al B P etc.
It looks like in some designs the vaporized metal is assisted by oxygen, i am guessing this would require the vacuum pump to be on full time, does the hot gases cause issues with the internals of the pump or vaporize the pump oil?
