Large-area (1 cm2), vertically aligned ZnGa2O4, Mn2+ doped ZnGa2O4 (ZnGa2O4:Mn2+) and Cr3+ doped ZnGa2O4 (ZnGa2O4:Cr3+ ) nanowire arrays were synthesized by a two-step thermal evaporation method using ZnO nanowire arrays as the templates followed by reaction with Ga and/or dopant (Mn ...
Germanium is an effective catalyst for the growth of highly aligned, closely packed polycrystalline Al 2 O 3 and amorphous SiO 2 nanowire bunches. The Ge-catalyzed nanowire growth exhibits interesting growth behavior not observed in conventional Au-catalyzed nanowire growth. Nanoscale ...
Gallium phosphide (GaP) nanowires were synthesized in a high yield by vapor-phase reaction of gallium vapor and phosphorus vapor at 1150 C in a tube furnace system. The nanowires have diameters in the range of 25100 nm and lengths of up to tens of micrometers. Twinning growth occurs in G ...
