The Ideal

In recent years the Cu3Au (110) surface has been studied by many authors to reveal its ordering structure and order-disorder transition phenomena. A 2×1 structure which corresponds to an ideal truncation of the ordered bulk crystal and a 4×1 reconstructed structure have been observed. Using ion scattering methods, McRae et al have determined the Au fractions in the first and the second layer at room temperature, which deviate from the ideal bulk value and indicate the segregation of Au to the surface. But the question how the atoms are rearranged in the 4×1 structure and why some of the Au stays in the second layer have not been answered. Another important question about Cu3Au (110) surface is whether the long period ordering structure (LPS) exists on the surface. In present work the Cu3Au (precise composition Cu71.7Au28.3) (110) surface is studied with Auger electron Spectroscopy (AES) and Reflection High Energy Electron Diffraction (RHEED) which have not been used to study the Cu3Au surface before.
