Anemone-like nanostructures for non-lithographic reproducible large-area and ultra-sensitive SERS substrates

Daglar, B.; Demirel, G. B.; Khudiyev, T.; Dogan, T.; Tobail O.; Altuntas, S.; Buyukserin F.; Bayındır, Mehmet (Royal Society of Chemistry, 2014)

The melt-infiltration technique enables the fabrication of complex nanostructures for a wide range of applications in optics, electronics, biomaterials, and catalysis. Here, anemone-like nanostructures are produced for the ...
Concentric ring structures as efficient SERS substrates

Cinel, N. A.; Cakmakyapan, S.; Ertas, G.; Özbay, Ekmel (Institute of Electrical and Electronics Engineers, 2013)

Plasmonic nanopatterned structures that can work as highly efficient surface-enhanced Raman scattering (SERS) substrates are presented in this study. A 'coupled' concentric ring structure has been designed, fabricated, ...
Validation of electromagnetic field enhancement in near-infrared through Sierpinski fractal nanoantennas

Cakmakyapan, S.; Cinel, N.A.; Cakmak, A.O.; Özbay, Ekmel (Optical Society of American (OSA), 2014)

We introduced fractal geometry to the conventional bowtie antennas. We experimentally and numerically showed that the resonance of the bowtie antennas goes to longer wavelengths, after each fractalization step, which is ...
