Lead-free piezoelectric materials of the future

Piezoelectric materials have fantastic properties: squeeze them and they generate an electrical field. And vice-versa, they contract or expand when jolted with an electrical pulse. With a name derived from the Greek word ...

Cooling chips with the flip of a switch

Turn on an electric field, and a standard electrocaloric material will eject heat to its surroundings as its internal dipoles reorder themselves. Do the same thing, and a negative electrocaloric material will absorb heat, ...

Towards 'unbreakable' message exchange

Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks.

Neuromorphic camera and machine learning aid nanoscopic imaging

In a new study, researchers at the Indian Institute of Science (IISc) show how a brain-inspired image sensor can go beyond the diffraction limit of light to detect miniscule objects such as cellular components or nanoparticles ...

Making insulator conduct

(Phys.org)—New results on the interaction of femto- and attosecond light pulses with a solid insulator hold promise for reaching electronic switching rates up to the petahertz domain.

Light pulses control graphene's electrical behavior

Graphene, an ultrathin form of carbon with exceptional electrical, optical, and mechanical properties, has become a focus of research on a variety of potential uses. Now researchers at MIT have found a way to control how ...

Speeding up electronics to light frequencies

(Phys.org)—Modern information processing allows for breathtaking switching rates of about a 100 billion cycles per second. New results from the Laboratory for Attosecond Physics (LAP) of Prof. Ferenc Krausz (Max Planck ...
