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. 1932-7447 10.1021/jp103670b https://hdl.handle.net/20.500.14352/43991 http://pubs.acs.org/doi/abs/10.1021/jp103670b http://pubs.acs.org Micro- and nanopyramids of Manganese-Doped Indium Oxide
