AB Sn-doped In2O3 arrow-shaped nanorods have been grown by a catalyst-free evaporation deposition method. Transmission electron microscopy (TEM) investigations reveal a complex defect structure consisting of nanoprecipitates, dislocation loops, and voids, in the core of the nanorods, extending all along the growth axis. The nanoprecipitates are Sn or Sn-rich and appear sometimes associated with small voids. The voids appear aligned in rows or discontinuous empty nanochannels along the nanorod core. TEM images depict the presence of surface ripples perpendicular to the growth direction, with typical distances of less than 10 nm. The relationship of the observed defect structure with a dislocation-driven growth of the nanorods is discussed.
