Titanium thin film oxidation
WebThe influence of strong electric fields (∼107 V/cm) on the growth, modification, and destruction of thin oxide films at the metal surfaces are studied for a titanium tip of a scanning tunneling microscope (STM) oxidized in oxygen at different tip potentials. The spectroscopic measurements show that, in sufficiently strong fields (V≤−7.5 V) …
