Mechanical behavior and magnetic separation of quasi-one-dimensional SnO₂ nanostructures: A technique for achieving monosize nanobelts/nanowires
(Georgia Institute of Technology, 2005-03-25)
The as-synthesized nanowires and nanobelts usually have a large size distribution. We demonstrate here a ball milling technique for narrowing the size distribution of oxide nanobelts and nanowires. High-resolution scanning ...
Toward high output-power nanogenerator
(Georgia Institute of Technology, 2008-04-29)
In this paper, the factors that determine the power output of a piezoelectric nanowire (NW) nanogenerator (NG) have been analyzed. The output current is the sum of those contributed by all of the NWs while the output voltage ...
Polar-surface dominated ZnO nanobelts and the electrostatic energy induced nanohelixes, nanosprings, and nanospirals
(Georgia Institute of Technology, 2004-02-09)
We report the controlled synthesis of free-standing ZnO nanobelts whose surfaces are dominated by the large polar surfaces. The nanobelts grow along the a axis, their large top/bottom surfaces are the ±(0001) polar planes, ...
Nanobelts as nanocantilevers
(Georgia Institute of Technology, 2003-04-28)
Semiconducting oxide nanobelts of ZnO have been sectioned and manipulated, for microelectromechanical systems, using an atomic force microscopy probe. Structurally modified nanobelts demonstrate potential for nanocantilever ...
Controlled synthesis and manipulation of ZnO nanorings and nanobows
(Georgia Institute of Technology, 2005-01-19)
An experimental procedure is presented for the controlled synthesis and manipulation of ZnO nanorings and nanobows at high purity and large yield. Atomic force microscopy manipulation of the nanostructures demonstrates ...
Recent Advances in High-k Nanocomposite Materials for Embedded Capacitor Applications
(Georgia Institute of Technology, 2008-10)
In this paper, a wide variety of high dielectric constant (k) composite materials which have been developed and evaluated for embedded capacitor application are reviewed. Current research efforts toward achieving high ...
Synthesis and characterization of Zn₁₋ₓMnₓO nanowires
(Georgia Institute of Technology, 2008-04-21)
Mn doped ZnO nanowires (NWs) were fabricated by a one-step vapor-solid process at 500°C. The doped Mn exists in the wurtzite lattice as substitutional atom without forming secondary phases. X-ray absorption near-edge ...
Novel Nano-Scale Conductive Films With Enhanced Electrical Performance and Reliability for High Performance Fine Pitch Interconnect
(Georgia Institute of Technology, 2009-02)
In this paper, a novel nano-scale conductive film which combines the advantages of both traditional anisotropic conductive adhesives/films (ACAs/ACFs) and nonconductive adhesives/films (NCAs/NCFs) is introduced for next ...
Direct synthesis of silicon nanowires, silica nanospheres, and wire-like nanosphere agglomerates
(Georgia Institute of Technology, 2000-04-24)
Elevated temperature synthesis has been used to generate virtually defect free SiO₂sheathed crystalline silicon nanowires and silica (SiO₂) nanospheres which can be agglomerated to wire-like configurations impregnated with ...
Nanoscale mechanical behavior of individual semiconducting nanobelts
(Georgia Institute of Technology, 2003-08-04)
Nanobelts are a group of materials that have a rectangle-like cross section with typical widths of several hundred nanometers, width-to-thickness ratios of 5–10, and lengths of hundreds of micrometers. In this letter, ...
