Microscopy Explores Nanowires' Weakest Link
2012-02-14 04:54:25

Individual atoms can make or break electronic properties in one of the world's smallest known conductors–quantum nanowires. Microscopic analysis at the Department of Energy's Oak Ridge National Laboratory is delivering a rare glimpse into how the atomic structure of the conducting nanowires affects their electronic behavior. The ORNL team's microscopy confirmed that deliberately introduced defects, which are only the size of a single atom, could turn a conducting nanowire into an...

Researchers at the Nano-Science Center at the University of Copenhagen have developed a new nano-technology platform for the development of molecule-based electronic components using the wonder material graphene. At the same time, they have solved a problem that has challenged researchers from around world for ten years.  Since its discovery in 2004, graphene has been called a wonder material, in part because it is 200 times stronger than steel, a good electrical conductor and is just...

Nanowires Welded With Light

At the nano level, researchers at Stanford have discovered a new way to weld together meshes of tiny wires. Their work could lead to innovative electronics and solar applications. To succeed, they called upon plasmonics. One area of intensive research at the nanoscale is the creation of electrically conductive meshes made of metal nanowires. Promising exceptional electrical throughput, low cost and easy processing, engineers foresee a day when such meshes are common in new generations of...

Imaeg 1 - New Microtweezers May Build Tiny 'MEMS' Structures
2012-01-18 04:53:54

Researchers have created new "microtweezers" capable of manipulating objects to build tiny structures, print coatings to make advanced sensors, and grab and position live stem cell spheres for research. The microtweezers might be used to assemble structures in microelectromechanical systems, or MEMS, which contain tiny moving parts. MEMS accelerometers and gyroscopes currently are being used in commercial products. A wider variety of MEMS devices, however, could be produced through a...

Just 100 nanometers in diameter, nanowires are often considered one-dimensional. But researchers at Northwestern University have recently reported that individual gallium nitride nanowires show strong piezoelectricity — a type of charge-generation caused by mechanical stress — in three dimensions. The findings, led by Horacio Espinosa, James N. and Nancy J. Farley Professor in Manufacturing and Entrepreneurship at the McCormick School of Engineering and Applied Science, were...

The smallest wires ever developed in silicon - just one atom tall and four atoms wide - have been shown by a team of researchers from the University of New South Wales, Melbourne University and Purdue University to have the same current-carrying capability as copper wires. Experiments and atom-by-atom supercomputer models of the wires have found that the wires maintain a low capacity for resistance despite being more than 20 times thinner than conventional copper wires in microprocessors....
