All-aluminum hierarchical plasmonic surfaces in the infrared

Ayas S.; Bakan, G.; Dana, A. (The Optical Society, 2016)

All-Aluminum metal-insulator-metal resonator structures withmultiple metal-insulator stacks showing resonances in the mid-infrared(MIR) are fabricated. Ultrathin native Al2O3 is used as the insulator layersenabling simple ...
Exploiting native Al2O3 for multispectral aluminum plasmonics

Ayas S.; Topal, A. E.; Cupallari, A.; Güner, H.; Bakan, G.; Dana, A. (American Chemical Society, 2014)

Aluminum, despite its abundance and low cost, is usually avoided for plasmonic applications due to losses in visible/infrared regimes and its interband absorption at 800 nm. Yet, it is compatible with silicon CMOS processes, ...
ZnO nanostructures on electrospun nanofibers by atomic layer deposition/hydrothermal growth and their photocatalytic activity

Kayaci, Fatma; Vempati, Sesha; Ozgit-Akgun, Cagla; Biyikli, Necmi; Uyar, Tamer (Materials Research Society, 2014)

A hierarchy of nanostructured-ZnO was fabricated on the electrospun nanofibers by atomic layer deposition (ALD) and hydrothermal growth, subsequently. Firstly, we produced poly(acrylonitrile) (PAN) nanofibers via ...
