Nanometer-scale layered structures based on thallium(III) oxide were electrodeposited in a beaker at room temperature by pulsing the applied potential during deposition. The conducting metal oxide samples were superlattices, with layers as thin as 6.7 nanometers. The defect chemistry was a function of the applied overpotential: High overpotentials favored(More)
Nanocrystalline films of 8-Bi 2,03 were electrodeposited at 65°C directly from alkaline solutions of tartrate-complexed Bi(III). This face-centered-cubic polymorph of Bi 20 3 is normally only stable at high temperatures (729-825'C). The material has the highest known oxide ion mobility. We propose that the high temperature form of the oxide is stabilized(More)
