A benchmark material that exhibits ultralow thermal conductivity is SnSe. We study the nonequilibrium phonon dynamics induced by an excited electron population using a framework combining ultrafast ...

Gao Peng's research group at the International Center for Quantum Materials, School of Physics, Peking University, has ...

Scientists have, for the first time, directly observed phonon wave dynamics within self-assembling nanomaterials unlocking ...

Scientists have unveiled a new observational technique that's sensitive to the dynamics of the intrinsic quantum jiggles of ...

The world’s strangest trampoline doesn’t bounce—it swings sideways and even glides around corners. But no one can jump on it, ...

Scientists have developed a liquid-phase electron microscopy technique that makes it possible to observe phonon dynamics in ...

Find more information on the Altmetric Attention Score and how the score is calculated. Phonon-assisted anti-Stokes photoluminescence (ASPL) up-conversion lies at the heart of optical refrigeration in ...

Recent technological advances have opened new exciting possibilities for the development of cutting-edge quantum devices, ...

The brains behind the trampoline – physicists from the University of Konstanz, the University of Copenhagen, and ETH Zurich – want to use it to demonstrate new methods of phonon transport. The ...

Why? The aim is to demonstrate improved methods of phonon transport – for example, for use in microchips, where phonons are directed through tight bends. Imagine a trampoline that is 0.2 millimetres ...

This is in sharp contrast with transistor applications of carbon nanotubes in which transconductance degrades considerably by electron-phonon scatterings unless their channels are made ultrashort ...
