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 ...

Reverse Chemical Switching of a Ferroelectric Film

(PhysOrg.com) -- Ferroelectric materials display a spontaneous electric polarization below the Curie temperature that can be reoriented, typically by applying an electric field. In this study, researchers from Argonne, Northern ...

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.

Low power, programmable cell array demonstrated by NEC

NEC Corporation announced today the successful demonstration of a low power programmable cell array using a rewritable and nonvolatile solid-electrolyte switch, "NanoBridge," integrated into a 90nm CMOS.

Using carbon to control the light

(Phys.org) —The flip of a light switch – a nano-scale light switch – may some day dramatically boost the speed of data transmission, from streaming movies to accelerating the most data-intense computation. Today, information ...
