Hall effect becomes viscous in graphene

Researchers at The University of Manchester in the UK have discovered that the Hall effect—a phenomenon well known for more than a century—is no longer as universal as it was thought to be.

Scientists go deep to quantify perovskite properties

Scientists led by Rice University and Los Alamos National Laboratory have discovered electronic properties in quantum-scale devices that are likely to impact the growing field of low-cost perovskite based optoelectronics.

Two-dimensional material shows promise for optoelectronics

A team of MIT researchers has used a novel material that's just a few atoms thick to create devices that can harness or emit light. This proof-of-concept could lead to ultrathin, lightweight, and flexible photovoltaic cells, ...

Graphene could yield cheaper optical chips

Graphene—which consists of atom-thick sheets of carbon atoms arranged hexagonally—is the new wonder material: Flexible, lightweight and incredibly conductive electrically, it's also the strongest material known to man.

Moth-inspired nanostructures take the color out of thin films

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" ...

How graphene and friends could harness the Sun's energy

(Phys.org) —Combining wonder material graphene with other stunning one-atom thick materials could create the next generation of solar cells and optoelectronic devices, scientists have revealed.

'Dark plasmons' transmit energy

Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.
