High quality factor photonic crystal nanobeam cavities [PDF]

Applied Physics Letters, 2009
We investigate the design, fabrication, and experimental characterization of high quality factor photonic crystal nanobeam cavities in silicon. Using a five-hole tapered one-dimensional photonic crystal mirror and precise control of the cavity length, we designed cavities with theoretical quality factors as high as 1.4×107.

Enhancing Fatigue Performance by Tuning of Residual Stresses in Welded Joints through Nanometallic Multilayer

Advanced Engineering Materials, Volume 28, Issue 1, January 2026.
This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...

On Nonlinear Bending Study of a Piezo-Flexomagnetic Nanobeam Based on an Analytical-Numerical Solution

Nanomaterials, 2020
Among various magneto-elastic phenomena, flexomagnetic (FM) coupling can be defined as a dependence between strain gradient and magnetic polarization and, contrariwise, elastic strain and magnetic field gradient.

Pioneering Carboxylated Zirconium Oxo Cluster Resist for Precision Nanoscale Patterning

Advanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
This study presents zirconium oxo cluster bonded with benzoic acid (Zr‐OCB) as organic–inorganic hybrid photoresist for electron beam lithography (EBL). High resolution patterns with a feature size of sub‐40 nm, a sensitivity of 1905 µC cm−2, a low line edge roughness of 3.1 nm, and excellent solution stability for up to six months are demonstrated for

Inverse Design in Nanophotonics via Representation Learning

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
This review frames machine learning (ML) in nanophotonics through a classification based on where ML is applied. We categorize methods as either output‐side, which create differentiable surrogates for solving Maxwell's partial differential equations (PDEs), or input‐side, which learn compact representations of device geometry.

Smart Cut Transfer of Wide‐Bandgap Materials: The Case of Diamond

physica status solidi (a), Volume 223, Issue 2, January 2026.
Adapting the Smart Cut process to diamond unlocks a new pathway for engineering ultrahard materials. Through controlled ion implantation and fracture along a buried sp²‐rich layer, thin transferred diamond films are obtained with preserved crystalline quality.
