| Abstract: | A method for preparing of atomical flat gold substrate was reported. A series of gold substrates were prepared with the method from 25 C to 270 C and were characterized by using Scanning probe Microscope(SPM). The results show that the mean roughness values of these gold substrates are smaller than 0.4 nm for areas of 25 μm2. A higher resolution image made by using Scanning Tunneling Microscope (STM) shows a hexagonal pattern of high spots with nearest neighbor spacing of 0.30±0.04 nm, which is consistent with a Au-(111) lattice. Meanwhile, self-assembled monolayer film of 1,6-hexanedithiol on the gold has been characterized by electrochemical cyclic voltammetry and X-ray photoelectron spectra. |
