Understanding photoacoustic signal formation in the presence of transparent thin films [PDF]

Photoacoustics
Strain-induced variation of the refractive index is the main mechanism of strain detection in photoacoustic experiments. However, weak strain-optic coupling in many materials limits the application of photoacoustics as an imaging tool.

Information advantage in sensing revealed by Fano-resonant Fourier scatterometry [PDF]

Nature Communications
Fano resonances in nanophotonic structures are attractive for sensing due to their ultanarrow resonant linewidths and high local fields. Conventional read out schemes rely on measuring a frequency shift in Fano scattering spectra as function of ...

Photonic crystal hydrogels based on highly reproducible molding method [PDF]

Scientific Reports
A lot of sensors using structural color are based on periodic nanostructures, or photonic crystals. So the nanostructures need to be fabricated with high reproducibility so that those sensors can be suitable for practical and commercial applications ...

Electrochemically-stimulated nanoscale mechanochemical wear of silicon

Friction, 2023
Mechanochemical reactions at the sliding interface between a single-crystalline silicon (Si) wafer and a silica (SiO2) microsphere were studied in three environmental conditions: humid air, potassium chloride (KCl) solution, and KCl solution with an ...

Divergence and efficiency optimization in polarization-controlled two-color high-harmonic generation

Scientific Reports, 2021
Improving the brightness of high-harmonic generation (HHG) sources is one of the major goals for next-generation ultrafast, imaging and metrology applications in the extreme-ultraviolet spectrum.

A force controlled tribometer for pre-sliding measurements at the nanometer scale

Frontiers in Mechanical Engineering, 2023
In the pre-sliding friction regime, interfaces partially stick and partially slip. The pre-slip is thought to be locally initiated at regions of the interface where the ratio of shear stress to normal stress exceeds a critical value.

The spectrum of a 1-μm-wavelength-driven tin microdroplet laser-produced plasma source in the 5.5–265.5 nm wavelength range

AIP Advances, 2021
We present a calibrated spectrum in the 5.5–265.5 nm range from a microdroplet-tin Nd:YAG-laser-produced plasma under conditions relevant for the production of extreme ultraviolet (EUV) light at 13.5 nm for nanolithography.

Plasmonic enhancement of photoacoustic strain-waves on gold gratings

AIP Advances, 2022
In this paper, we report on the time-dependent strain-wave-induced changes in the reflection and diffraction of a gold plasmonic grating. We demonstrate efficient excitation of strain waves using enhanced absorption at and around the surface plasmon ...

Nanofabrications of T shape gates for high electron mobility transistors in microwaves and THz waves, a review

Micro and Nano Engineering, 2021
High electron mobility transistors (HEMTs) are the basic building block in microwave monolithic integration circuits (MMICs) for broad applications in micrometer (0.3–100 GHz), millimeter (100–300 GHz) and tera [1] hertz (300 GHz–10 THz) wave.
