abstract = {Adhesion of biological systems is often made possible
through thin elastic layers, such as human skin. To address
the question of when a layer is sufficiently thin to become
adhesive, we extended Green’s function molecular dynamics
(GFMD) to account for the finite thickness of an elastic
body that is supported by a fluid foundation. We observed
that thin layers can much better accommodate rough
counterfaces than thick structures. As a result, the contact
area is enlarged, in particular, when the width of the layer
w approaches or even falls below the short-wavelength cutoff
λs of the surface spectra. In the latter case, the
proportionality coefficient between area and load scales is
(w/λs)3 , which is consistent with Persson’s contact
mechanics theory.},
