Observations of the Cu3Au(001) phase transition using a novel low energy electron diffraction system.
01 January 1984
A novel low energy electron diffraction (LEED) system has been used to record the peak intensities and angular profiles of LEED beams from Cu3Au(001) surface. The LEED system uses position- sensitive counting detection to make digital records of LEED patterns with angular resolution 0.3degrees. Observations and profile analyses on both the (00) and (1/2 1/2) beams in the temperature range 350-900 K are reported. Experimental procedures of annealing and Auger spectroscopy are described in detail.
