Reversible doping: Hydrogen flips switch on vanadium oxide

If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks to a new study ...

Doped graphene nanoribbons with potential

Graphene is a semiconductor when prepared as an ultra-narrow ribbon – although the material is actually a conductive material. Researchers from Empa and the Max Planck Institute for Polymer Research have now developed a ...

Researchers invent a switch that could improve electronics

Researchers at the University of Pittsburgh have invented a new type of electronic switch that performs electronic logic functions within a single molecule. The incorporation of such single-molecule elements could enable ...

Carriers reject kill switch for stolen smartphones (Update)

Samsung Electronics, the world's largest mobile phone manufacturer, has proposed installing a built-in anti-theft measure known as a "kill switch" that would render stolen or lost phones inoperable, but the biggest U.S. carriers ...

An advance toward ultra-portable electronic devices

Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a ...
