Fig. 1: Free energy plot of the most stable oxygen-terminated diamond (110) surface phases.
From: Coexistence of carbonyl and ether groups on oxygen-terminated (110)-oriented diamond surfaces
The shaded region represents the convex hull of the free energy of adsorption, ΔGads. ΔGads is presented as a function of the chemical potential of oxygen, ΔμO, in the gas phase. The free energy of adsorption is shown for the most stable phases listed in Table 1. A full free energy plot of all phases can be seen in Supplementary Fig. 1. Orthographic ball-and-stick visualizations of the first three carbon layers of the phases are shown as viewed ‘front on’ from the [001] direction, with carbon and oxygen atoms shown in gray and red respectively. The unit cell outlines of the surrounding structures are shown in black dashed lines with surface axes also presented.
