Mechanically generated surface chirality at the nanoscale.
A substrate coated with an achiral polyimide alignment layer was scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid crystal orientation. The resulting noncentrosymmetric topography resulted in a chiral surface that manifests itself at the molecular level. To show this unambiguously, a planar-aligned negative dielectric aniostropy achiral nema...
متن کامل1 An Introduction to Chirality at the Nanoscale
Scientists have been fascinated by chirality, meaning rightor left-handedness, in the structure ofmatter ever since the concept first arose as a result of the discovery, in the early years of the nineteenth century, of natural optical activity in refracting media. The concept of chirality has inspired major advances in physics, chemistry and the life sciences [1, 2]. Even today, chirality conti...

The field of chirality has recently seen a rejuvenation due to the observation of chirality in inorganic nanomaterials. The advancements in understanding the origin of nanoscale chirality and the potential applications of chiroptical nanomaterials in the areas of optics, catalysis and biosensing, among others, have opened up new avenues toward new concepts and design of novel materials. In this...
متن کاملNonlinear Superchiral Meta-Surfaces: Tuning Chirality and Disentangling Non-Reciprocity at the Nanoscale
Circularly polarized light is incident on a nanostructured chiral meta-surface. In the nanostructured unit cells whose chirality matches that of light, superchiral light is forming and strong optical second harmonic generation can be observed.
