ABSTRACT:
A method of growing films composed of low-melting-point materials from a feed material whose constituents have large differences in vapor pressure. In the system disclosed, the feed material is contained within an ampoule and delivered in the form of a melt to a heated environment whose temperature is higher than the temperature of vaporization of the constituent of the feed material having the highest vaporization temperature, thereby to effect flash vaporization of the liquid and thus avoid changes in composition or phase separation.
