organic carbon adsorption microroughness of Si surface native oxide Coulomb's force field-enhancement

To investigate the adsorption mechanism of organic carbon on Si surface, Si surface was examined by AFM and XPS, after dipping into the water which contains the organic carbon. The measurement deta of Ra indicates that the geometrically uneven surface such as the step or microfacet does not serve as the dominant adsorption site for the organic carbon. The mesured data of C_1s and the thickness of the native oxide strongly indicates that the adsorption of the organic carbon has the close relationship with the native oxide growth. For the adsorption mechanism of the organic carbon, new model which assumes the field-enhancement due to the Coulomb's force was discussed.
