Evolution of electronic structure and spectral evaluation in single-crystal Mn3 O4 nanorods

Single-crystal Mn₃O₄ nanorods with tetragonal structure have been successfully prepared by a chemical reaction route. Transmission electron microscopy (TEM) and high-resolution TEM studies prove that the single-crystal Mn₃O₄ nanorod is smooth and straight, and that the geometrical shape is structurally perfect. We investigated the electronic characteristics of Mn₃O₄ nanorods by various spectral evaluations. The present study confirms that the hybridization between oxygen 2p and manganese 3d orbits plays an important role when considering electronic structures of Mn₃O₄ nanorods. © 2006 American Institute of Physics.
