High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Bimodal Spin Switch Emerging from Hybridized 2D MoS2/Ferromagnet Interfaces

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization‐driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière's model. These results highlight the « 2D spinterfaces » key role in unlocking

Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

open access: yesAdvanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic
