Breaking the symmetry of nanostructures, either in-plane or out-of-plane, is crucial for achieving chiral BICs. Finally, the review discusses the role of nonlinear optics in enhancing chiral signals.
Recent experiments in our laboratory have shown that under a continuous and dynamic dissolution-crystallization process, a racemic population of ethylenediamine sulfate crystals can be driven into ...
hexagonal symmetry plane. In addition, the integration of chiral-structural-color microdomes into contact lenses opens up ...
