Nanowires grown on graphene have surprising structure

(Phys.org) —When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy.

Effect of image-charges on electron transport better understood

Electron transport through a single molecule offers a highly promising new technology for the production of electronic chips. However it is difficult to make a good conducting connection between the molecule and the metal ...

X-rays illuminate nitrogen's role in single-layer graphene

(Phys.org)—Researchers using x-rays to study a single-atom-thick layer of carbon, called graphene, have learned new information about its atomic bonding and electronic properties when the material is "doped" with nitrogen ...

James' bond: A graphene / nanotube hybrid

(Phys.org)—A seamless graphene/nanotube hybrid created at Rice University may be the best electrode interface material possible for many energy storage and electronics applications.

Microtechnology: Miniature magnetic switches

Transistors are commonly used in electronics as switches to turn an electrical current on or off. For applications that require a very large ratio between the on and off current, however, it is necessary to use mechanical ...

Nanotubes find niche in electric switches

New research from Rice University and the University of Oulu in Oulu, Finland, finds that carbon nanotubes could significantly improve the performance of electrical commutators that are common in electric motors and generators.
