Impact of A‐Site Cation Substitution on Electronic and Optical Properties of 0D Perovskite Derivatives A4PbCl6 (A = Li, Na, K, Rb, Cs)

open access: yesAdvanced Photonics Research, EarlyView.
The isolated [PbCl6]4‐ octahedra, embedded in an alkali cation lattice, define the zero‐dimensional (0D) character of A4PbCl6. This work deciphers how the A‐site cation identity (from Li to Cs) governs the local electrostatic environment, thereby providing a precise strategy for tuning electronic structures and optical properties. Zero‐dimensional (0D)

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

open access: yesAdvanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

open access: yesAdvanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...
