Differences in Schottky bar-rier heights and ideality factors of both structures are shown to be related with the modification of theoxygen-terminated diamond/metal interface configuration. Oxide formation, oxide thickness variationsand interfacial oxygen redistribution, associated with thermal treatment are demonstrated. Ideality fac-tors close to ideality (nWC= 1.02 and nZr= 1.16) are obtained after thermal treatment and are shown to berelated with the relative oxygen content at the surface (OCRWC= 3.03 and OCRZr= 1.5). Indeed, thermaltreatment at higher temperatures is shown to promote an escape of oxygen for the case of the WC diode,while it generates a sharper accumulation of oxygen at the metal/diamond interface for the case of Zrdiode. Therefore, the metal-oxygen affinity is shown to be a key parameter to improve diamond-basedSchottky diodes.}, organization = {This work was made possible through grants from theSpanishMinistry of Economy and Competitiveness (ref: TEC2014-54357-C2-2-R, HiVolt-nano project) and from the European H2020Program (ref: SEP-210184415, Green Diamond project).
