Abstract

Hetero-junction beaded nanowires were synthesized from the mixture of Sn and In metals by the gas-transport. These nanowires were characterized with XRD, SEM, TEM. Many singlecrystal In2O3 beads epitaxially grown along the axis of the single-crystal core SnO2 nanowires form
the beaded nanowires. The In2O3 beads have defi nite orientations along the [200] direction of the core SnO2 nanowires and show regular rhombohedral morphology. A possible growth mechanism for the beaded nanowires is proposed.
