Single crystalline mesoporous silicon nanowires.
Herein we demonstrate a novel electroless etching synthesis of monolithic, single-crystalline, mesoporous silicon nanowire arrays with a high surface area and luminescent properties consistent with conventional porous silicon materials. These porous nanowires also retain the crystallographic orientation of the wafer from which they are etched. Electron microscopy and diffraction confirm their s...

متن کاملSingle-Crystalline Mesoporous Molybdenum Nitride Nanowires with Improved Electrochemical Properties
We report single-crystalline mesoporous molybdenum nitride nanowires (meso-Mo3N2-NWs) prepared by topotactic reaction using single-crystalline molybdenum oxide nanowires. The single-crystalline nature of meso-Mo3N2-NWs was clearly observed by field-emission transmission electron microscopy. The meso-Mo3N2-NWs exhibited mesoporous structure with 45 m/g in specific surface area and 4.6 nm in aver...
متن کاملSingle-crystalline LaB6 nanowires.
Lanthanum hexaboride nanowires produced by chemical vapor deposition are single-crystalline and grown along the [111] direction. Streaks appearing in the electron diffraction spots indicate the lateral direction perpendicular to the nanowire growth axis.
متن کاملSingle-crystalline CeB(6) nanowires.
Considered to be one of the best electron emission materials, CeB6 nanowires are of great scientific and industrial interest. CeB6 nanowires of square cross section with about 50 nm in lateral dimension and more than several micrometers in length have been successfully produced using a chemical vapor deposition method. The nanowires are grown in the 100 lattice direction, and both the tip top a...
