Chirality, Volume 38, Issue 5, May 2026.Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

ChemNanoMat, Volume 12, Issue 5, May 2026.Dimensionality control in Yb3+/Ho3+‐doped KCa2Nb3O10 reveals how layered oxides and their exfoliated two‐dimensional Ca2Nb3O10− nanosheets function as upconversion thermometers. Temperature sensing is achieved via the luminescence intensity ratio of green/red Ho3+emissions, while post‐treatments enable photon‐assisted surface‐state engineering, linking

Merging of defect modes in a superlattice of one-dimensional metamaterials photonic crystals
AIP Advances, 2019 The optical properties are investigated in a new type of one-dimensional photonic crystal, which consists of two-layer unit cells. The first layer consists of a material with a negative refractive index (NIM) and the other is made of AlxGa1−xAs with a ...

InfoMat, Volume 8, Issue 5, May 2026.Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

'Hexagon-type' photonic crystal slabs based on SOI [PDF]
, 2002 In this paper we discuss the design of a novel category of photonic crystal slabs (PCS) and as an example, we consider structures based on SOI wafers. Fabrication issues related to lithographic accuracy are addressed, too.

Superlensing properties of one-dimensional dielectric photonic crystals
, 2009 We present the experimental observation of the superlensing effect in a slab of a one-dimensional photonic crystal made of tilted dielectric elements. We show that this flat lens can achieve subwavelength resolution in different frequency bands.

Efficient Color Filters Based on Fano-Like Guided-Mode Resonances in Photonic Crystal Slabs
IEEE Photonics Journal, 2018 We numerically report designs of color filters comprising of 2-D photonic crystal (2D-PhC) slabs of square lattice of air holes. The filter principle is based on excited Fano-like guided-mode resonances (GMRs) in the visible regime with high-quality ...

Classifying topology in photonic crystal slabs with radiative environments
npj NanophotonicsIn the recent years, photonic Chern materials have attracted substantial interest as they feature topological edge states that are robust against disorder, promising to realize defect-agnostic integrated photonic crystal slab devices. However, the out-of-
