Surface waves can help nanostructured devices keep their cool

Due to the continuing progress in miniaturization of silicon microelectronic and photonic devices, the cooling of device structures is increasingly challenging. Conventional heat transport in bulk materials is dominated by ...

On the trail of causes of radiation events during space flight

Scientists have made significant progress in understanding the sources of radiation events that could impact human space-flight operations. Relativistic electron precipitation (REP) events are instances when high energy electrons ...

Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

Physicists make electrical nanolasers even smaller

Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported ...

Scientists develop a technique to dynamically curve a photon jet

Scientists at Tomsk Polytechnic University jointly with international colleagues have found a simple technique to dynamically curve a photonic jet, turning it into a photonic hook. The method was published in Optics Letters. ...

Physicists nudge atoms within less than a trillionth of a second

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The ...

Temporal aiming with temporal metamaterials

Tailoring and manipulating electromagnetic wave propagation has been of great interest within the scientific community for many decades. In this context, wave propagation has been engineered by properly introducing spatial ...

Physicists obtain molecular 'fingerprints' using plasmons

Scientists from the Center for Photonics and 2-D Materials of the Moscow Institute of Physics and Technology (MIPT), the University of Oviedo, Donostia International Physics Center, and CIC nanoGUNE have proposed a new way ...
