摘要：

Self-assembled monolayers of decanethiol on Au(111) have been investigated using high resolution scanning tunneling microscopy (STM). After the annealing of the as-adsorbed densely packed c(2 root 3 x 4 root 3)R30 degrees structure and before the formation of a previously described low density (11.5 x root 3) stripe phase three different phases with intermediate molecular surface density have been observed. We present highly resolved and distortion-corrected STM images for both the (7.5 x root 3) stripe phase and the meshlike structure. We describe a mixed (7.5/11.5 x root 3) stripe phase that shows a switching of the stripe arrangement. (C) 2000 Elsevier Science B.V. All rights reserved.
