Product description:
This
type of effusion cell is designed for the evaporation of materials such
as germanium, tin, gold, silicon, copper etc. A single tantalum wire is
used for the heating system and PBN spacers for the electrical
isolation. The heating system is surrounded by several tantalum foils
to minimize heat dissipation and to concentrate the thermal power
within the evaporation zone. The design is optimized with respect to
thermal stability in order to obtain highest flux stability over an
extended period of time. PBN crucibles are standard with this type of
effusion cells. Other crucible materials are possible on request.
