Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

open access: yesSmall, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Enhanced Light Extraction of Flip-Chip Mini-LEDs with Prism-Structured Sidewall

open access: yesNanomaterials, 2019
Current solutions for improving the light extraction efficiency of flip-chip light-emitting diodes (LEDs) mainly focus on relieving the total internal reflection at sapphire/air interface, but such methods hardly affect the epilayer mode photons.

Effect of pH, milling time, and Isobam content on porous silicon nitride ceramics prepared by gel casting

open access: yesAdvanced Powder Materials, 2023
As a non-toxic copolymer of isobutylene and maleic anhydride, Isobam is successfully used as a dispersant and a gelling agent for fabricating porous Si3N4 ceramics by gel casting.

Mitigating Residual FAI for Air‐Stable FAPbI3 LEDs

open access: yesSmall, EarlyView.
Treating FAI‐rich FAPbI3 perovskite films with the multifunctional molecule DEAET, combining a protonated amine and a thiol group, effectively regulates residual surface organic‐halide species, suppresses non‐radiative recombination, and modifies interfacial energetics. The resulting near‐infrared perovskite LEDs achieve 14% external quantum efficiency

Plasma‐Enabled Simultaneous Synthesis and Nano‐Anchoring of TiO2−x Nanolayers on Mesoporous Bio‐Silica for Effective Photodegradation of Tetramethylammonium Hydroxide

open access: yesSusMat, EarlyView.
A defect‐rich TiO2−x nanolayer was simultaneously synthesized and nano‐anchored on a mesoporous bio‐silica (diatomite) through a rapid, low‐temperature atmospheric‐pressure plasma process in aqueous media. The optimized TiO2−x/bio‐silica composite (DE 700) exhibits oxygen vacancies, an anatase–rutile heterointerface, broad solar‐spectrum absorption ...

Review of Amorphous Gallium Oxide: From Material Synthesis to Device Applications

open access: yesphysica status solidi (a), Volume 223, Issue 15, 5 August 2026.
Amorphous gallium oxide (a‐Ga2O3) is reviewed as a promising ultra‐wide‐bandgap material for solar‐blind UV photodetectors. The influence of structural disorder, defect states, and trap‐assisted transport on optical and electronic performance is examined.
