An MOCVD route to In2O3 one-dimensional materials with novel morphologies

Abstract

We have successfully synthesized one-dimensional (1-D ) indium oxide (In2O3) arrays by the metalorganic chemical vapor deposition (MOCVD) method. We have characterized the products by means of X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM). The SEM images showed that the 1-D materials with serrated surfaces had cross-sections in the shape of an acute triangle. The XRD and TEM studies revealed that the 1-D materials possessed a single-crystalline cubic structure and that the growth occurred preferentially along the [111] direction.
