Coulomb blockade in anodised titanium nanostructures

We investigate the electrical transport properties of narrow titanium (Ti) wires which are thinned by anodic oxidation. At temperatures below 1 K the current–voltage ( IV) characteristics of the resulting Ti/TiO x nanostructures exhibit a zero current state due to the occurrence of Coulomb blockade....

Description
Summary:We investigate the electrical transport properties of narrow titanium (Ti) wires which are thinned by anodic oxidation. At temperatures below 1 K the current–voltage ( IV) characteristics of the resulting Ti/TiO x nanostructures exhibit a zero current state due to the occurrence of Coulomb blockade. An indium gate electrode is placed on top of the anodised region, and the modulation of the conductance as a function of the gate voltage is investigated.
