High-reflectivity broadband distributed Bragg reflector lattice matched to ZnTe

, 2009
We report on the realization of a high quality distributed Bragg reflector with both high and low refractive index layers lattice matched to ZnTe. Our structure is grown by molecular beam epitaxy and is based on binary compounds only. The high refractive

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Preparation and novel photoluminescence properties of the self-supporting nanoporous InP thin films

Scientific Reports, 2020
Self-supporting nanoporous InP membranes are prepared by electrochemical etching, and are then first transferred to highly reflective (> 96%) mesoporous GaN (MP-GaN) distributed Bragg reflector (DBR) or quartz substrate. By the modulation of bandgap, the

Game‐Making for Cultural Change and Empowered Youth Participation

Journal of Computer Assisted Learning, Volume 42, Issue 2, April 2026.
ABSTRACT Background Game‐making has the potential to foster cultural participation and empowerment, yet its role as a form of culture‐making remains underexplored. Existing approaches to cultural engagement often overlook the creative and participatory possibilities of game‐making for addressing pressing cultural challenges and promoting youth ...

Can neutral and ionized PAHs be carriers of the UV extinction bump and the diffuse interstellar bands?

, 2011
Up to now, no laboratory-based study has investigated polycyclic aromatic hydrocarbon (PAH) species as potential carriers of both the diffuse interstellar bands (DIBs) and the 2175 A UV bump.

Optically pumped DBR-free semiconductor disk lasers

Optics Express, 2015
We report high power distributed Bragg reflector (DBR)-free semiconductor disk lasers. With active regions lifted off and bonded to various transparent heatspreaders, the high thermal impedance and narrow bandwidth of DBRs are mitigated. For a strained InGaAs multi-quantum-well sample bonded to a single-crystalline chemical-vapor deposited diamond, a ...

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

Macromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...
