Abstract : Gold films deposited by evaporation onto amorphous substrates at a wide variety of temperatures were examined by x-ray and electron-reflection diffraction, as well as by resistivity measurements. It was found that: (a) the (111) texture predominates at all deposition temperatures and appears almost exclusively between 370 and 500C; (b) the hexagonal partial structure, first noted by others in cold-worked bulk gold, appears in electron diffraction in this temperature range, along with the forbidden (110) reflection; (c) the deposition process introduces large concentrations of vacancies, which cluster under annealing into quite stable complexes. A large observed increase in resistivity and a contraction of the lattice as measured by x-ray diffraction are related to these vacancies. (Author)
