[labnetwork] Electron beam evaporation of Ge

[Shivakumar Bhaskaran]

Sunanda,

I used graphite and fabmate (lesker) crucible for Germanium, I didn't have any issue. I only fill 50% volume of crucible

Hi,

For Ge, I see that the mostly recommended crucible is Al2O3. But, we tried and observe charging effects here. However, Kurt Lesker recommends Graphite. Can anyone share your experience with Ge deposition through ebeam evaporation?
Should it be graphite or Al2O3 ...?

thanks and best regards,
sunanda
