Laser structuring for control of coupling between THz light and phonon modes
X. W. Wang, G. Seniutinas, A. Balcytis +8
Modification of surface and volume of sapphire is shown to affect reflected and transmitted light at THz spectral range. Structural modifications were made using ultra-short 230 fs…
Efficient X-ray generation from gold colloidal solutions
Koji Hatanaka, Matteo Porta, Frances Camille P. Masim +5
Hard X-ray generation for Au nanoparticle dispersion was systematically investigated for different particle diameters ranging from 10 to 100 nm with a narrow size distribution of +…
Au-Ag-Cu nano-alloys: tailoring of permittivity
Yoshikazu Hashimoto, Gediminas Seniutinas, Armandas Balcytis +2
Precious metal alloys enables new possibilities to tailor materials for specific optical functions. Here we present a systematic study of the effects of a nanoscale alloying on the…
UV-photoelectric effect for augmented contrast and resolution in electron microscopy
Gediminas Seniutinas, Armandas Balcytis, Saulius Juodkazis
A new tool providing material contrast control in scanning electron microscopy (SEM) is demonstrated. The approach is based on deep-UV illumination during SEM imaging and delivers…
Percolation threshold gold films on columnar coatings: characterisation for SERS applications
Armandas Balcytis, Tomas Tolenis, Xuewen Wang +4
Percolation of gold films of ~15 nm thickness was controlled to achieve the largest openings during Au deposition. Gold was evaporated on 300-nm-thick films of nanostructured porou…
