Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

open access: yesAdvanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Dual‐Array Nano Configuration for High‐Performance Metastable β Titanium Alloys

open access: yesAdvanced Science, EarlyView.
This work resolves a fundamental paradox in metastable alloys by establishing a novel dislocation‐phase coupling mechanism, enabling dynamic microstructure control for simultaneous thermal stability and deformability. Geometrically ordered α‐nanograins achieve unprecedented 500°C strength‐ductility synergy (863 MPa UTS, 78.3% elongation).

Ferromagnetic Interlayer Exchange Coupling in Magnetic Topological Insulator Sandwich Heterostructures

open access: yesAdvanced Science, EarlyView.
A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...
