Single-molecule force spectroscopy experiments demonstrate that hydrogenation and oxidation of polycrystalline diamond effectively control molecular adhesion (see figure). Aging changes these properties and originates from the rapid formation of a thin and resistant contamination layer, as well as degradation of the artificial surface termination on longer time scales. This aging also affects the wettability, morphology, and the electrical properties of the surfaces.
