Interferometer -based Technology for Optical Nanoscale Inspection

Measurement Science Review, 2014
We demonstrate the interferometer-based approach for nanoscale grating Critical Dimension (CD) measurements and prove the possibility to achieve no worse than 10 nm accuracy of measurements for 100 nm pitch gratings.

Dynamical Modulation of Dual‐Band Thermal Emission in a Graphene‐2D‐hBN‐LiV2O5 Heterostructure

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A van der Waals heterostructure combining graphene, 2D‐hBN, and LiV2O5 enables dynamically tunable dual‐band mid‐infrared thermal emission with narrow spectral features. Plasmon–phonon strong coupling yields five hybrid polariton branches, whereas coupled‐oscillator models quantify mode mixing and Rabi splittings (up to 27.72 meV via hBN‐thickness ...

Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.

Freestanding Polymer Metasurface Supporting Higher‐Order Optical Resonances for Strong Field Enhancement in TMD Monolayers

Small, Volume 22, Issue 35, 23 June 2026.
A freestanding polymer metasurface is developed to enhance light emission from atomically thin semiconductors. By supporting higher‐order optical resonances that concentrate electromagnetic fields at the surface, the platform significantly improves coupling between light and WS2 monolayer.

Scalable simple liquid deposition techniques for the enhancement of light absorption in thin films: Distributed Bragg reflectors coupled to 1D nanoimprinted textures

AIP Advances, 2017
Light trapping within a light absorbing medium is a key to highly efficient thin film solar cells. We propose a large-scale procedure based on materials with low absorption for the fabrication of combined Distributed Bragg Reflector (DBR) and grating ...

High‐Barrier Amorphous Al2O3 Film Deposited via Magnetic Field‐Confined for Ultrastable Hygroscopic Scintillators

SmartMat, Volume 7, Issue 3, June 2026.
The moisture‐induced degradation of hygroscopic scintillators limits their performance and lifespan in radiation detection. A 100 nm amorphous Al2O3 film, deposited at room temperature via FCVA with pulsed magnetic field confinement, offers high optical transmittance and ultralow moisture permeability.
