摘要：
Desorption process of octadecanethiol self-assembled monolayers (SAMs) on Au(111) was investigated by thermal desorption spectroscopy (TDS). TD spectra for several desorption species including decomposition fragments of the adsorbed molecules were observed at an elevated temperature. Scanning tunneling microscopy (STM) study shows that decomposition in SAMs is strongly related to striped phase formed via phase transition caused by desorption of molecules from densely packed monolayers.
