Laminated Multilayer Optical Waveguides Enabled by Floating Film Transfer

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
A scalable floating film transfer process enables the lamination of sub‐micron polymer films into high‐quality multilayer optical waveguides. The method preserves optical performance, allows precise control over layer stacking, and supports the integration of high‐index‐contrast polymer/air gratings for efficient mode coupling in advanced photonic ...

Molecular Layer Deposited Aluminum‐Based Hybrid Resist for High‐Resolution Nanolithography and Direct Ultra‐High Aspect Ratio Pattern Transfer

Advanced Materials Technologies, Volume 11, Issue 3, 5 February 2026.
This study demonstrates an aluminum‐based hybrid photoresist synthesized via molecular layer deposition (MLD) using trimethylaluminum and hydroquinone. The resist achieves sub‐20 nm resolution and virtually infinite silicon etch selectivity, enabling 40 nm‐wide, micrometer‐tall nanostructures.

Engineering Thermal Emission with Enhanced Emissivity and Quality Factor Using Bound States in the Continuum and Electromagnetically Induced Absorption

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A metal‐based thermal metasurface supporting bound states in the continuum is demonstrated and experimentally shown to achieve a record‐high quality factor of 202 and high emissivity of 0.82. The design offers thermally stable, narrowband mid‐infrared emission, making it ideal for high‐precision gas sensing applications.

Grid‐Shaped, Vertically Aligned Carbon Nanotube Architectures for Electrical, Optical, and Mechanical Bolometers

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
The small geometry of nano/micro sensor devices, down to 3 × 3 µm2, makes them ideal for reliable large‐scale integration into sensor arrays for single‐use biomedical, industrial, and security applications. These devices allow for the efficient conversion of ultraviolet to terahertz radiation into electrical or optical output signals using simple ...

Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence

Advanced Science, Volume 13, Issue 9, 13 February 2026.
An innovative dual‐spectroscopy approach resolves the debate over GaAsBi's emission temperature sensitivity. By combining temperature‐dependent photoluminescence and transmission spectroscopy, the method decouples the contributions of band‐tail states from the intrinsic band‐edge behavior.

Deuteration Induced Electron‐Phonon Coupling Modulation: Suppressing Energy Dissipation and Enhancing Carrier Separation in Organic Photocatalysis

Advanced Science, Volume 13, Issue 7, 3 February 2026.
During charge transport, photogenerated carriers exchange energy with lattice vibrations, influencing photocatalytic performance. The deuteration strategy enhances exciton dissociation and suppresses non‐radiative energy loss, significantly improving photocatalytic hydrogen evolution.
