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 ...

A research team including members from the University of Michigan have unveiled a new observational technique that's ...

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 ...
