    • Care should be taken that the inhibition of the Si surface oxidation is not interpreted as an absolute stability of the modified Si surface. First, the amount of silicon oxide that is formed after a certain period of time can be below the detection limits in the XPS measurements. Second, at defect sites in the monolayer oxidation of the Si surface can certainly occur, although this reaction will probably be on a much slower time scale compared to the oxidation of the H-terminated surfaces. Water is required for the oxidation (see ref 9), and the (hydrophobic parts of the) organic layer will make it difficult for the water molecules to reach the Si surface. Another point that has to be taken into account is that the oxidation of the H-terminated Si surface takes much longer than the observed decay of the charge carrier lifetimes, as was already discussed in the Introduction. The monolayers used here inhibit the oxidation of the Si surface for a long time, but - as observed for the H-terminated surfaces - this does not imply that the decay of the charge carrier lifetimes is similarly decelerated.
