Surface reconstruction phases of Au/Si(001) system were studied with scanning tunnelling microscopy and low energy electron diffraction in a converge range of 0.3 to 2.5ML and an annealing temperature range of ambient to 800C, and a structure diagram was presented. In addition to the structures reported previously, two new phases were discovered; an 8 x 2 structure in a low coverage region and a () structure in coexistence with c(8 x 2) and 5 x 3 structures. In the latter structure a characteristic phase boundary that was considered to serve as a generation center for 5 x 3 structure was observed.
