Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

Advanced Physics Research, EarlyView.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

Advances in Regulating Strategies and Applications of Ferroelectric Materials

Advanced Physics Research, EarlyView.
To meet the demand for precise control of performance in nanoelectronic devices, this paper systematically reviews the latest advances in controlling ferroelectric properties through strategies such as external field modulation, low‐dimensional confinement, interface engineering, and topological structure design.

Rational Design of Donor‐Acceptor Oligomers for Enhanced Charge Separation

Advanced Physics Research, EarlyView.
How can molecular symmetry be broken to maximize photoinduced charge separation? Through first‐principles analysis of 22 DTP‐based donor‐acceptor ternary oligomers, this work establishes that combining architectural asymmetry with site‐selective acceptor fluorination creates an ideal electrostatic landscape for frontier orbital segregation.

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary
