We investigate the microstructure of the reconstructed Au(001) surface using ultra-high vacuum transmission electron microscopy (UHV-TEM). Bulk single crystal Au(001) surfaces were prepared via standard metallographic techniques followed by repetitive cleaning of the surface with ion milling and annealing. After a clean surface was obtained, the (001) surface was found to reconstruct into two nearly orthogonal domains of dimensions (5 × n) where n ranges between 15 and 21. The unit cell vectors of the surface cell are parallel to the 〈110〉 directions of the unreconstructed fcc (001) surface. Analysis of the diffuse scattering and dark field micrographs indicates that the surface is sheared with a complicated domain and periodicity structure which depends upon the local geometry of the substrate.
