Humidity effects on nano-oxidation are investigated using a dynamic force microscope in the humidity range of 30–60%. Oxide size and detected faradaic current increased with relative humidity and applied voltage. The aspect ratios of fabricated oxides at various humidities are approximately of the same magnitude. Scanning probe microscope nano-oxidation in the dynamic mode is less subject to the relative humidity than that in the contact mode.
