[labnetwork] Ebeam deposition of Gold

[Michael Rooks]

It's true that gold will alloy with tungsten. However, carbon crucibles 
are not ideal for gold evaporation, since gold will agglomerate around 
carbon particles. The gold film will be lumpy if carbon is accidentally 
evaporated from the crucible. Molybdenum crucibles are much better.
