Abstract:

The growth of epitaxial single crystal copper films 5000 to 8000 angstroms thick on a fresh rock salt clevage heated to 320C is described. Disposition took place in a given vacuum at a rate of 10 to 15 Asec. The resultant film being annealed at the same temperature for 1 hr. The orientation of the epitaxial film and the degree of perfection of its single crystal structure were studied by a method based on the channelling effect, using a 130 to 180 keV proton beam. Films deposited on the NaCl face had an accurate orientation throughout their whole thickness. Author
