Using the Rh(3+) ion (Rh d(6)) in a regular octahedral coordination, which forms fully occupied t(2g)(6) and empty e(g)(0) as a result of ligand-field splitting, we demonstrated that Rh-doped ZnGa(2)O(4) had midgap states created by t(2g)(6) and e(g)(0) that had

This paper reports the formation of self-organized nanoporous gallium oxide by anodization of solid gallium metal. Because of its low melting point (ca. 30 °C), metallic gallium can be shaped into flexible structures, permitting the fabrication of nanoporous anodic oxide
