ABSTRACT
A faradaic current on the order of a sub-pico-ampere was detected while fabricating two-dimensional oxide nanostructures on H-passivated Si(001) surfaces. The detected faradaic current has been shown to faithfully reflect the degree of probe oxidation with a clear dependence on the variation of voltage and the tip speed. The faradaic current in dynamic mode can serve as a sensitive monitor of the nano-oxidation reaction for implementing precise closed-loop control of the oxide growth.

    The introduction of AlO as the diffusing species can be seen as an attempt to bridge the gap between the two scientific communities: those working on the oxidation of metals and those working on the oxidation of silicon. The attempt is, however, not successful and would have been more successful...

    A method is presented to form metallic nanowires and nanochannels by guided self-assembly. The method relies on an initial plasma-enhanced chemical vapor deposition of a silicon oxide film with altered chemistry on a silicon wafer, and the cracking of the film due to tensile stresses upon...
