In the most simple case, a wire or sheet of metal is used as both a container and heater for the material to be evaporated. By running a current through this metal, enough heat is generated to cause vaporization of the evaporation material. Tungsten, molybdenum, or tantalum are the usual choices because they have melting points higher than most evaporation materials.
