RT Journal Article T1 Three dimensional nanowire networks and complex nanostructures of indium oxide A1 Magdas, Dana A. A1 Cremades Rodríguez, Ana Isabel A1 Piqueras de Noriega, Javier AB Elongated In2O3 micro- and nanostructures have been grown by two-step thermal treatments of compacted InN powder, at temperatures between 350 and 700 degrees C. Different thermal treatments have been found to induce the growth of structures with different sizes and morphologies as wires, rods, or arrows. The experimental conditions leading to the different structures, as well as the evolution of the structures during the treatments, have been investigated. Some treatments lead to large scale formation of three dimensional networks of the mentioned structures. The mechanism of network formation is discussed. The structures have been characterized by cathodoluminescence, scanning electron microscopy, and x-ray diffraction.
