(a) Transfer of valence electrons from the diamond surface to an adsorbed liquid electrolyte layer according to Maier et al. [36]. The adsorbed water layer is assumed to be slightly acid due to the dissolution of atmospheric CO₂; (b) cross section through a hydrogen terminated diamond sensor (top) and onto a processed device (bottom).
