Abstract

Novel SnO₂-In₂O₃ heterostructured nanowires were produced via a thermal evaporation method, and their possible nucleation/growth mechanism is proposed. We found that the electronic conductivity of the individual SnO₂-In₂O₃ nanowires was 2 orders of magnitude better than that of the pure SnO₂ nanowires, due to the formation of Sn-doped In₂O₃ caused by the incorporation of Sn into the In₂O₃ lattice during the nucleation and growth of the In₂O₃ shell nanostructures. This provides the SnO₂-In₂O₃ nanowires with an outstanding lithium storage capacity, making them suitable for promising Li ion battery electrodes.
