Plasmonic enhancement of photoacoustic strain-waves on gold gratings

open access: yesAIP 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 ...

Femtosecond Laser Direct‐Write Plasmonic Nanolithography in Dielectrics

open access: yesSmall Science, 2022
Plasmon‐based devices have founded numerous applications in photonics based on optically excited strong near‐field effect at nanoscale. So far, the large‐area fabrication of periodic plasmonic nanostructures is still challenging due to a small write ...

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

open access: yesMicro 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.

Direct Patterning of a Cyclotriveratrylene Derivative for Directed Self-assembly of C60 [PDF]

open access: yes, 2011
A novel apex-modified cyclotriveratrylene (CTV) derivative with an attached thiolane-containing lipoic acid linker was directly patterned onto gold substrates via dip-pen nanolithography (DPN).

Material-resolved and thickness-sensitive lensless imaging using high-harmonic generation: From diffractive shear interferometry to ptychography [PDF]

open access: yesEPJ Web of Conferences
Microscopy with table-top high-harmonic generation (HHG) sources enable high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-specific absorption edges available in this spectral range.
