Abstract

Polished low-index diamond planes are often taken to be hydrogen terminated. Previous work has shown a partial monolayer of oxygen on the surface. We have made use of the 16O(α, α)16O resonance at 3.045 MeV to study the oxygen on the diamond surface with increased sensitivity. With a method for producing ultra-thin diamonds, new research in diamond is possible. Ultra-thin diamonds were made by damaging thick diamonds with MeV carbon ions, annealing the damage out of the surface region leaving a graphitised (Bragg peak) layer below, and electrochemical etching with de-ionized water. This produced a few μm thick and a few mm diameter sized samples. Transmission channelling, with a 4 MeV α-microbeam was used to determine the position of the surface oxygen on a (1 0 0) oriented diamond.
