TL;DR: One-dimensional nanostructures have uniform diameters of less than approximately 200 nm and are referred to as "nanowires" as mentioned in this paper, which include single-crystalline materials having different chemical compositions.
Journal ArticleDOI
Titanium nitride as a plasmonic material for visible and near-infrared wavelengths
Gururaj V. Naik,Jeremy L. Schroeder,Xingjie Ni,Alexander V. Kildishev,Timothy D. Sands,Alexandra Boltasseva +5 more
TL;DR: In this article, the excitation of surface-plasmon-polaritons on titanium nitride thin films was demonstrated and the performance of various plasmonic and metamaterial structures with the material as the plammonic component was discussed.

Separation of thin films from transparent substrates by selective optical processing
TL;DR: In this article, a thin GaN epitaxially grown on a sapphire substrate is separated from the substrate by laser irradiation at a wavelength at which the GaN is strongly absorbing, e.g., 248 nm.
Journal ArticleDOI
Equilibrium limits of coherency in strained nanowire heterostructures
TL;DR: In this paper, a variational approach is used to show that nanowire heterostructures are more effective at relieving mismatch strain coherently, in which the mismatch strain is shared by the overlayer and underlayer, and could as well be partially accomodated by the mesh.
Journal ArticleDOI
Damage-free separation of GaN thin films from sapphire substrates
TL;DR: In this article, gallium nitride thin films were successfully separated and transferred onto Si substrates using single 38 ns KrF excimer laser pulses directed through the transparent substrate at fluences in the range of 400-600 mJ/cm2.
