Measuring circular phase-dichroism of chiral metasurface

Nanophotonics, 2019
The ability of chiral media to differentiate circularly polarized light is conventionally characterized by circular dichroism (CD) which is based on the difference in the absorption of the incident light for different polarizations.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Enhancement of Dielectric Breakdown Strength and Recoverable Energy Density in Three‐Dimensional Heterointerfaces on BaTiO3–PbZrO3–PbTiO3 Films via Room‐Temperature Nano‐Clustering

Advanced Functional Materials, EarlyView.
A room‐temperature aerosol deposition process yields multiphase nano‐clustered dielectric capacitors containing discrete BaTiO3, PbZrO3, and PbTiO3 crystals. This architecture creates three‐dimensional heterointerfaces that induce interfacial charge trapping and effectively inhibit breakdown propagation.

The Chirality Induction and Modulation of Polymers by Circularly Polarized Light [PDF]

Symmetry, 2019
Chirality is a natural attribute nature of living matter and plays an important role in maintaining the metabolism, evolution and functional activities of living organisms. Asymmetric conformation represents the chiral structure of biomacromolecules in living organisms on earth, such as the L-amino acids of proteins and enzymes, and the D-sugars of DNA

Dye‐Initiated Chirped Cholesteric Polymer Networks Exhibiting Broadband Dissipative Chiral Photonic Bands

Advanced Functional Materials, EarlyView.
A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.
