RT Journal Article T1 Micro- and nanopyramids of Manganese-Doped Indium Oxide A1 Maestre Varea, David A1 Martínez Velasco, I. A1 Cremades Rodríguez, Ana Isabel A1 Amati, M. A1 Piqueras De Noriega, Francisco Javier AB Mn-doped In(2)O(3) nanopyramids have been grown by a catalyst-free thermal process at 700 degrees C using InN and Mn(2)O(3) powders as precursors. Energy dispersive spectroscopy, as well as X-ray photoelectron spectroscopy, demonstrate the presence of Mn in the pyramids in a content below 1 at. %. In addition to pyramids, nanowires with diameters of about 100 nm grow during treatments at 800 degrees C. Luminescence has been studied by cathodoluminescence in the scanning electron microscope, showing emissions at 1.9, 2.65, and 3.3 eV. Dopant incorporation into the nanostructures and their oxidation states, as well as the effect on the electronic structure, have been measured and discussed.
