Comparison of methanethiol adsorption on Ag(110) and Cu(110)-chemical issues related to self-assembled monolayers

Article Abstract:

The comparative study of the adsorption and thermal decomposition of methanethiol, which is the simplest alkanethiol, on the Ag(110) and Cu(110) surfaces using surface science techniques, temperature programmed desorption (TDP), low energy electron diffraction (LEED), and Auger electron spectroscopy (AES) is described. The greater affinity of Cu for sulfur compared to Ag controls the methanethiol adsorption and decomposition mechanism on the two metals.

Methanethiol chemisorption on Cu(110): chemical and geometrical issues related to self-assembly

Article Abstract:

A study of the adsorption of methanethiol on the clean Cu(110) and the sulfur-passivated Cu(110) surface with the time-of-flight electron-stimulated desorption ion angular distribution (TOF-ESDIAD) method, temperature-programmed desorption (TPD), and low energy electron diffraction (LEED) is presented. Results show that sulfur passivated copper surface is chemically stable and forms a template for the ordered absorption of methanethiol.

The precursor mediated chemisorption of venyl bromide on Si (100) c (4x2)

Article Abstract:

The high-resolution electron energy loss spectroscopy (HREELS) study on the adsorption states of venyl bromide as a function of temperature and coverage is presented. From this study, the kinetic parameters were obtained from the precursor state to the chemisorption state.
