Solid-phase sintering method was used to dope Nd and Sm ions at the Y sites of Y₂MgTiO₆ ceramics, forming a solid solution and significantly increasing the Q×f value. The analysis of chemical bonds ...
“We found record-high coherence for phonons at low temperatures, when the vibration completed nearly a thousand cycles before fading,” the study’s first author said, according to Rice University’s ...
Nonlinear vibrations in lattice systems represent a fascinating departure from conventional harmonic behaviour, where the classical linear superposition principle is supplanted by complex dynamics ...
A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...
New measurements in germanium reveal how excited electrons drive lattice vibrations that govern energy flow and heating in semiconductors. (Nanowerk News) Whether in a smartphone or laptop, ...
Researchers have shown, for the first time with very high time and spatial resolution, that electrons in certain two-dimensional materials only follow the motion of the atomic nuclei with a delay.
One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists to understand for the first time how and why certain materials conduct ...
A team co-led by UC San Diego and the University of Michigan reports that short pulses of sound could remotely drag a structural defect through a metamaterial lattice, potentially letting researchers ...
