Damaging of boats during nickel evaporation

2008-05-30
Hi,

   I met similar problem when I evaporated Al by
tungsten boat. When Al melted in tungsten boat, the
evaporation rate suddenly reduced and after a while
the boat was "ate" by the melted Al. So I can not
obtain thick Al film. Does anyone know this and give
some hint? Thank you very much.
