Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$
The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system

Trilayer oxide architecture introduces interfacial asymmetry and surface roughness in SRO/BTO/SRO heterostructures, creating a locally modulated polar and magnetic landscape. This design enhances the topological‐Hall‐like response, achieving a broad 5–90 K stability window and a maximum ρTHE of 0.8 µΩ cm, demonstrating an effective route to amplify ...

CW‐Pumped Amplified Spontaneous Emission From Thermally Evaporated CsPbBr3 Films
Thermally evaporated CsPbBr3 thin films sustain amplified spontaneous emission from short‐pulse toward quasi‐continuous‐wave excitation. Time‐resolved spectroscopy, controlled excitation, and substrate engineering reveal how excitation duration governs optical‐gain stability.
