    ABSTRACT: We carried out in-situ X-ray reflectivity study of nine n-alkane chains (CnH2n+2) on Si substrate, n in the range of 17-30. These films formed under vacuum at equilibrium vapor pressure of the respective alkane molecule. For all the alkanes studied we found a bilayer structure on the substrate, a higher density vertical layer at the air-film interface with the layer thickness equal to the all-trans length of the respective molecule, and a lower density layer below it with the molecules lying horizontal on the substrate. This model was earlier proposed for C32 films on Si by Volkmann et al.11 We observe that this model can fit the entire range of data from C17 to C30 in our experiments.
