Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

Advanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

Temperature‐Dependent Optical and Polaritonic Properties of Excitons in hBN‐Encapsulated Monolayer TMDs

Advanced Optical Materials, EarlyView.
A comparative study of the optical and polaritonic properties of excitons in hBN‐encapsulated monolayer TMDs close to the homogeneous linewidth is presented. Reflection spectroscopy with transmission‐line modeling enables extraction of the complex permittivities and demonstrate their ability to host surface‐exciton‐polaritons.

Ferroelectric Fluids for Nonlinear Photonics: Evaluation of Temperature Dependence of Second‐Order Susceptibilities

Advanced Optical Materials, EarlyView.
Nonlinear optical susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as smectic A ferroelectric phase, are determined. The materials investigated include archetypal molecular architectures as well as mixtures showing room‐temperature ferroelectric phases.

Ionic Density‐Controlled Conjugated Polyelectrolytes for Interface Engineering in Inverted Colloidal PbS Quantum‐Dots Infrared Photodetector

Advanced Optical Materials, EarlyView.
This study demonstrates that conjugated polyelectrolytes with tunable ionic density can act as effective interfacial layers in inverted PbS quantum dot photodiodes. By enhancing dipole orientation and defect passivation at the ITO/QD interface, the devices exhibit suppressed dark current, improved photocurrent, and a record near‐infrared detectivity of

Mid‐Infrared Intersubband Transitions in p‐Type SiGe Parabolic Quantum Wells

Advanced Optical Materials, EarlyView.
The design, growth, and characterization of hole‐doped Ge‐rich SiGe parabolic quantum wells exhibiting mid‐infrared intersubband transitions are reported. Structural analyses confirm the parabolic compositional profile, while optical spectroscopy supported by tight‐binding simulations demonstrates strong and temperature‐stable absorption up to room ...
