EFM 3
The EFM 3 is designed for epitaxial thin film growth from sub-monolayer to complex multilayer systems, with evaporation rates varying from 1/10 monolayer per minute to several monolayers per second. The precisely defined evaporant beam profile allows highly uniform deposition on the sample. The deposition area is determined by the choice of three different easily exchangeable exit apertures and the distance from the source to the sample. Integrated into each EFM 3 is a z-shift for material feed when using rods or simply to optimize the distance between the electron beam filament and material to be evaporated either from a rod or crucible.
