Broadband All-angle Negative Refraction by Optimized Phononic Crystals
Scientific Reports, 2017 All-angle negative refraction (AANR) of phononic crystals and its frequency range are dependent on mechanical properties of constituent materials and their spatial distribution. So far, it is impossible to achieve the maximum operation frequency range of

Self‐Assembly of a Colloidal Honeycomb Crystal in Silico for Topological Valley Photonics
Small, Volume 22, Issue 62, 6 November 2026.The self‐assembly of a colloidal honeycomb crystal is demonstrated in computer simulations, using an assembly strategy that not only suppresses the formation of real‐space topological defects observed experimentally but also yields topological photonic properties in reciprocal space.

Time-modulated phononic crystal of oscillating bimetallic rods
Mathematical treatment of space- and time-modulated structures is similar. However, the practical realization of time dependence on elastic properties is a much more difficult problem than the fabrication of a phononic crystal where elastic properties ...

Anomalous Sub‐Band Gap Emission at Room Temperature in Mixed‐Dimensional WS2/Cu2O Heterostructures
Small, Volume 22, Issue 62, 6 November 2026.Monolayer WS2 on Cu2O produces a room‐temperature sub‐bandgap emission from the hybrid interface. Spectroscopy and electrical bias measurements indicate that this emission arises primarily from WS2‐modified Cu2O defect states rather than interlayer excitons.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, Volume 36, Issue 81, 8 October 2026.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
