Metal nanostructures are, nowadays, extensively used in applications such as catalysis,
electronics, sensing, optoelectronics and others. These applications require the possibility to …

Metal films of nanoscale thickness, deposited on substrates and exposed to laser heating,
provide systems that involve several interesting multiphysics effects. In addition to fluid …

We here show that Ag-Au bimetallic nanoparticles (NPs) can be produced by dewetting an
Ag/Au bilayer film coated on glass using a nanosecond-pulsed laser beam. Elemental …

Recent progress in submicron-and nano-fabrication technologies has led to the emergence
of novel photonic structures such as optical nanoantennas and metasurfaces. Real-life …

Novel experimental data on microstructuring of thin (60 nm) gold films by femtosecond laser
pulses are presented and discussed. Material modifications are induced by different laser …

Ripples or laser-induced periodic surface structures (LIPSS) are obtained on metallic films
(Cr, Ti, and W) by femtosecond laser pulses working at both fundamental (775nm) and …

Nano-islands are entities (droplets or other shapes) that are formed by spontaneous
dewetting (agglomeration, in the early literature) of thin and very thin metallic (especially …

We show here that the morphological pathway of spontaneous dewetting of ultrathin Ag films
on SiO 2 under nanosecond laser melting is dependent on film thickness. For films with …

The fabrication of precise 2D Au nanoparticle arrays over a large area is presented. The
technique was based on pre-patterning of the substrate before the deposition of a thin Au …

We report high optical enhancement in Ag/Au alloys and porous gold nanostructures using
Surface Enhanced Raman Spectroscopy (SERS) technique. Scanning electron microscopy …
