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.
