Investigations of thermally induced decomposition of adsorbed dpmH molecules showed that there are no significant products of desorption of carbon containing fragments of the molecule, i.e. most of the carbon atoms incorporate into the silicon surface causing it to reconstruct to a c(4x4) phase at exposures below a¼ 0.15 L. At higher exposures formation of SiC islands is observed. These findings demonstrate that schemes to deposit materials from organometallic compounds containing b-diketone ligands onto clean Si(100)-2x1 surface cannot result in an ordered interfacial structure as carbon incorporation into the substrate is inevitable.aThis work, bConstrained cluster values (see text for explanation), cZPE uncorrected energy difference. ... ethyl vinyl ketone (CH3CH2COCHCH2)21 2.8 ( 5.0) -41.3 allyl alcohol (CH2CHCH2OH)24 7.4 (-4.6) -41.0 acaca 6.1 (-3.0) -19.9 dpmHaanbsp;...
