Exposure to oxygen is usually detrimental for materials and devices as it leads to undesirable surface oxidation or even deeper corrosion. However, experiments with hydrogen-terminated H-diamond show that oxygen adsorption plays an instrumental role in inducing the p-type surface conductivity. Using first-principles calculations, we explore how the surface-physisorbed molecular O2 serves as an electron acceptor in the transfer doping of diamond. On the other hand, calculations reveal that in a chemisorbed state, oxygen groups sub
