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 ...

Two stopped light pulses interact with each other

(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...

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 ...

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.

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.

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 ...
