The room-temperature (RT) adsorption of dibromoethylene on Si(100)2x1 has been investigated by X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (TPD) mass spectrometry. The C 1s and Br 3d XPS spectra indicate the presence of a mono-σ bonded vinyl bromide adspecies (30%) and a di-σ bonded vinylene adspecies (70%) on Si(100)2x1, which suggests dehalogenation of dibromoethylene...
The adsorption of azomethane, and azomethane pre-cracked to form methyl and dinitrogen species, on Si(100) has been studied using XPS and thermal desorption techniques. Azomethane adsorbs with appreciable sticking probability at 300 K, most probably producing an adlayer containing a mixture of molecularly adsorbed and partially dissociated species. N = N bond cleavage dominates the partial decomposition...
