Scientist Creates Three-Atom-Wide Nanowire

Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today’s integrated circuits.The technique represents an exciting new way to manipulate matter at the nanoscale and should give a boost to efforts to create electronic circuits out of atomic monolayers, the thinnest possible form factor for solid objects.“This will likely stimulate a huge research interest in monolayer circuit design,” Lin said. “Because this technique uses electron irradiation, it can in principle be applicable to any kind of electron-based instrument, such as electron-beam lithography.”One of the intriguing properties of monolayer circuitry is its toughness and flexibility.“If you let your imagination go, you can envision tablets and television displays that are as thin as a sheet of paper that you can roll up and stuff in your pocket or purse,” said University Distinguished Professor of Physics and Engineering at Vanderbilt University, Sokrates Pantelides.SourceAlso: Learn about a Zinc Oxide Nanowire Interphase.

Scientists Demonstrate Electrical Properties of Topological Insulators

Scientists at the U.S. Naval Research Laboratory (NRL) have demonstrated for the first time that one can electrically access the remarkable properties predicted for a topological insulator (TI). They used a ferromagnetic metal/tunnel barrier contact as a voltage probe to detect the spin polarization created in the topologically protected surface states when an unpolarized bias current is applied. This accomplishment identifies a successful electrical approach that provides direct access to the TI surface state spin system, significantly advances our fundamental understanding of this new quantum state, and enables utilization of the remarkable properties these materials offer for future technological applications.

Bending Light with a Tiny Chip

Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at Caltech.

MELF Resistor Series

Stackpole Electronics Inc., Raleigh, NC, announces that its surface mount metal film MELFs, the MLF and MLFM Series offers cooler operating temperatures at full rated power. The cylindrical shape provides a termination that is far more thermally efficient than comparable size flat chip resistors. They are ideally suited for medical instrumentation, monitoring, and test equipment.

Printing Inkjet-Based Circuits

A team of researchers from Georgia Tech, the University of Tokyo, and Microsoft Research have developed a novel method to rapidly and inexpensively make electrical circuits by printing them with commodity inkjet printers and off-the-shelf materials. For about $300 in equipment costs, anyone can produce working electrical circuits in the 60 seconds it takes to print them.
