Micrometer Scale Adhesion on Nanometer-Scale Patchy Surfaces:  Adhesion Rates, Adhesion Thresholds, and Curvature-Based Selectivity. This is closely related to the fact that ellipsometry measurements provide an extra measurable physical quantity, the change in ellipticity at the surface, which has a weaker but different dependence on surface coverage and layer thickness. 5 publications. Recent success in the use of multi-wavelength ellipsometry to monitor and control high density reactive ion etching of Graphene, the single layer of graphite, has been the focus of many researchers internationally because of its unique electronic properties. The characterization of graphene films deposited on various substrates other than SiO 2 has been a challenging task thus far.
