Knudsen Type Vacuum Evaporation Source
Keywords: Vaccum evaporation, High vapour pressures, Thin film, Vaccum deposition
AbstractVarious types of resistively-heated evaporation sources are used for the vacuum deposition of materials in thin film form. However, the life of such boats or crucibles is short. This paper describes a versatile crucible for Knudsen type effusion process of evaporation for the preparation of thin films of sublimating materials, which have high vapour pressures at temperatures below 1000 degree centigrade. One representative micrograph of a thin film of CdSe obtained by vacuum evaporation from this crucible is also reported.
