Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3

open access: yesAdvanced Materials, EarlyView.
Through precise epitaxial engineering, the cubic and paraelectric KTaO3${\rm KTaO}_3$ is transformed into a robust ferroelectric. By leveraging lattice‐mismatched substrates to apply controlled epitaxial strain, a stable ferroelectric ground‐state is achieved with a transition temperature as high as 475 K, establishing KTaO3${\rm KTaO}_3$ as a highly ...

Radiation‐Matter Interaction in Chemical Vapor Deposition‐Grown Two‐Dimensional Tungsten Disulfide

open access: yesAdvanced Materials Interfaces, EarlyView.
Gamma irradiation tunes the magnetic properties of CVD‐grown WS2 material. Moderate irradiation doses induce low‐temperature ferromagnetic‐like behavior, whereas higher doses suppress the magnetic response because of increased defect formation. These findings provide insight into defect‐mediated magnetism in 2D TMDs and could be relevant to future ...

Engineering Exciton g‐Factors With Light in Type‐II Heterostructures

open access: yesAdvanced Optical Materials, EarlyView.
All‐optical approaches have emerged as cutting‐edge alternatives for ultrafast, energy‐efficient, and spatially localized tuning and switching of material properties. In our work, we demonstrate how light intensity alone can be leveraged to engineer g‐factors from a single‐type of carrier in type‐II heterostructures through Coulomb‐induced wavefunction

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

open access: yesAdvanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Optical control of RKKY coupling and perpendicular magnetic anisotropy in a synthetic antiferromagnet

open access: yesNature Communications
Synthetic antiferromagnetics (SAF) provide an excellent platform for antiferromagnetic spintronics. Recently, the voltage-control of the Ruderman–Kittel–Kasuya–Yosida (RKKY) interaction in SAFs was studied experimentally.

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

open access: yesAdvanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...
