Revealing Two Operation Modes of Perovskite Light‐Emitting Diodes Through Overshoot Pulses

Advanced Photonics Research, EarlyView.
Short, high‐intensity overshoot pulses (OSPs) may be generated by perovskite light‐emitting diodes (PeLEDs) depending on electrical pump pulse parameters, offset and afterpulse voltages. OSPs reveal two PeLED operation modes: the recombination mode, favorable for the conventional EL but preventing OSPs, and the accumulation mode, enabling the formation

Boosting the Magnetic Response of a Composite Nanostructure in the Near‐Visible Region with a Fano Resonance

Advanced Photonics Research, EarlyView.
Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.

Enhanced Trapping with an Optimized Graphene‐Based Bowtie Plasmonic Nanotweezer: Design, Analysis, and Bioanalytical Applications

Advanced Photonics Research, EarlyView.
A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

Engineering of Double Absorber Organic‐Perovskite Solar Cells for >34% Efficiency with V2O5 as Back Surface Field Layer

Advanced Photonics Research, EarlyView.
This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.

Toward Rapid Low‐Cost Fabrication of Single‐Nanowire Photodetectors via the Utilization of Dielectrophoresis

Advanced Photonics Research, EarlyView.
A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile
