Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Dimensionality‐Driven Emerging Phenomena in Hybrid Metal Halides
Small Structures, Volume 7, Issue 6, June 2026.Emergent Phenomena Governed by Octahedral Connectivity and Dimensionality. Hybrid metal halides are unique among semiconductors in that their inorganic octahedral networks can be rationally assembled in 3D, 2D, 1D, and 0D forms, enabling dimensionality to assist as a powerful control knob over structure, electronic properties, excitations, and ...

Optimizing doubly-resonant photonic crystal cavity modes for second harmonic generation
We optimize a photonic crystal slab for the generation of second harmonic. The optimization consists in two steps. In the first step a regular photonic crystal, consisting in a triangular lattice of circular holes in a dielectric slab, is optimized by ...

Numerical Analysis of Dual-wavelength Photonic Crystal Slab Microcavities
, 2007 本論文以模擬方式探討雙波長光子晶體平板微共振腔之輻射特性。此結構之雙波長為對應到藍光與黃光波長，兩互補色光能夠混合成為白光進而應用在照明上。本論文裡我們利用時域有限差分法作為數值模擬的工具。為設計雙波長光子晶體平板微共振腔，首先探討合適的光子晶體平板微共振腔型式，使之有兩個共振模態，同時對應之共振頻率能夠接近互補色光。接著藉由調整微共振腔周圍空氣洞的大小或位置探討其和輻射特性之間的關係。此調整可使兩共振頻率分開並接近藍光與黃光。接著也探討雙波長光子晶體平板耦合微共振腔之輻射特性 ...
