Abstract:

An ultra-high vacuum evaporator system was developed for depositing pure, epitaxial films. Pressures of 10 to the -10 power torr have been obtained. A tensile test device was incorporated to permit straining the film-substrate composites while still in the clean UHV environment. Preliminary load-displacement curves were obtained for polycrystalline silver substrates with and without gold films. Techniques were investigated for separating gold films from mica and sodium chloride substrates. An apparent grown-in compressive strain was observed as the film is relieved during separation from a sodium chloride substrate. Preliminary tensile tests of these free-films were conducted. Recommended future experiments as well as recommended modifications of equipment and techniques are given. Appended is a bibliography of literature references pertinent to this project with a coded notation of primary subject matter. Author
