Atomic layer deposition method was used to grow thin films consisting of ZrO2 and MnOx layers. All depositions were carried out at 300 oC. Some characteristics the manganese(III)acetylacetonate ozone process investigated, such as crystallinity dependence growth rate on temperature. partly crystalline in their as-deposited state. Zirconium oxide contained cubic tetragonal phases ZrO2, while mang...
Using a combination of high-angle annular dark-field scanning transmission electron microscopy and atomically resolved electron energy-loss spectroscopy in an aberration-corrected transmission electron microscope we demonstrate the possibility of 2D atom by atom valence mapping in the mixed valence compound Mn3O4. The Mn L(2,3) energy-loss near-edge structures from Mn2+ and Mn3+ cation sites ar...
Abstract The hydrothermal process was used to prepare Mn 3 O 4 /x%GO nanocomposites (NC’s) having different ratios of the nanoparticles (NP’s) on surface graphene oxide (GO) sheet. SEM image showed that NP’s were distributed over GO HRTEM images exhibited lattice fringe arising from (101) plane interplanar d-spacing 0.49 nm decorating GO. electronic absorption spectra NC’s also show broad bands...
