We have characterised the submonolayer assembly of C60F48 molecular surface acceptors on the hydrogen terminated (100) diamond surface using scanning tunneling microscopy and X-ray photoelectron spectroscopy, and explored the influence this assembly has on the energy level alignment which governs surface transfer doping. Following deposition, disordered multilayered islands are observed. Annealing to 90∘C causes a transition from dewetting multi-layered islands to a single wetting layer at sufficiently high coverage, accompanied by a change in the energy alignment between the C60F48 and the diamond surface which consequently decreased the carrier density induced by transfer doping by 20%.
