Methylamine adsorption on and desorption from Silicon (100)

Article Abstract:

The adsorption of several simple methylamines on the Si(100)-(2 x 1) surface is examined with the help of Auger electron spectroscopy (AES), thermal desorption spectroscopy, low-energy electron diffraction. The conclusion states that the surface saturation coverage of trimethylamine on Si(100) is 0.26 manolayers, consistent with the photoemission results, while both methylamine and dimethylamine appear to saturate at about 0.48 monolayers.

Density functional study on the interaction of a polycyclic aromatic molecule and the silicon (001) surface

Article Abstract:

A study is conducted to investigate the reaction of acenaphthylene (ACN) with the Si(001) surface is explored by means of density functional cluster model calculations. The findings indicate that also kinetics factors contribute to the high selectivity of the adsorption process and are consistent with recent experimental data, evidencing that ACN binds to the Si(001) surface through the 1,2-alkene unit.
