Photonics: Graphene boosts on-chip light detectors

The fabrication of high-performance light detectors—important for computers and mobile devices—using graphene integrated onto a chip is reported in three independent studies published online this week in Nature Photonics.

Redefining electrical current law with the transistor laser

(PhysOrg.com) -- While the laws of physics weren't made to be broken, sometimes they need revision. A major current law has been rewritten thanks to the three-port transistor laser, developed by Milton Feng and Nick Holonyak ...

Small optical force can budge nanoscale objects

(PhysOrg.com) -- Engineering researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers.

Long predicted but never observed: A new kind of quantum junction

A new type of quantum bit called a "phase-slip qubit", devised by researchers at the RIKEN Advanced Science Institute and their collaborators, has enabled the world's first-ever experimental demonstration of coherent quantum ...

Fundamental flaw in transistor noise theory discovered

(PhysOrg.com) -- Chip manufacturers beware: There's a newfound flaw in our understanding of transistor noise, a phenomenon affecting the electronic on-off switch that makes computer circuits possible. According to the engineers ...

Scientists bend nanowires into 2-D and 3-D structures

(PhysOrg.com) -- Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional ...
